Hi 😀

Could you post some more pics of your rig? The side panel window isn't something I see often these days and I doubt I have any cases like that myself, that's a nice touch (also that your case is beige) 😀

Have you checked the insides of your VX550 PSU? Might be bad caps.
And does your "new" Cooler Master PSU also come with a blue LED fan? I used to use a RS450...something for my old main rig (A64 s939 Venice), but always felt like the ratings on that PSU were a bit exaggerated so I don't know how good yours really is. Mine didn't blow up though and I'd still use it in a rig that doesn't require a heavy duty PSU (though yours has much higher ratings so you should be fine regarding that).

The SuperPi Modded is basically an old version of SuperPi that I found years ago as I was kinda bothered by SuperPi not displaying fractions of a second (only whole seconds) but the versions of SuperPi that did show those fractions would not run on 9x.

This version does (it's why I uploaded that version) BUT it always crashed after having done the first run (I think I actually needed a reset or something similarly annoying). However, all subsequent runs would run fine (on 9x at least) so I figured it had something to do with the log file it writes after the run is completed. The modded part is just the original SuperPi I found (I think someone else already modded it before so I'm not even sure it's an "official" release) with a result log file added by me with a dunny result so it won't crash after the first run.

For NT-based Windows I'd recommend using a more original version of SuperPi as those displayed fractions of a second by default.
One problem is that I think the original poster of the SuperPi thread wasn't me so I can't add the "XP version" of SuperPi and I only use the modded SuperPi when I intend to run it on a 9x OS. I never tried the modded SuperPi outside Windows 9x so no idea if it displays the same issues.

Those 865 boards I really like, I should rebuild my own one 😀
Your 865 board is LGA775?

Your GF7950GT is AGP? Nice! I should get me one of those, though I fear I'm a bit late to the party when it comes to getting these cards while they are still affordable, nice rig! 😁

The case was a dumpster find and had the original Micron 845 motherboard in it and almost every cap on it leaking and/or glued over on the top, I get a lot of Micron machines here but I guess its not that surprising being not far from their main facility. It was a lot of time and hand cramps cutting the side panel to fit the Plexiglas in it but apart from looking nice its really dense and blocks a lot of the sound inside the case. Also added a 60mm and a odd 94mm fan as intake on this case have them both running on 5V so they are quiet.

I opened up the VX550 no bulging caps but on the little board that the thermal sensors and the fan plugs into there was a tiny glob of solder bridging a resistor to a empty spot on the board I don't think it was supposed to be like that as it was barely connected. The PSU doesn't have many hours on it got it NIB at thrift store the fan would never speed up and sometimes would continue to run after the PC would shut down since I flicked that glob of solder off fan will go quite fast now I think it was overheating before haven't put a heavy load to it yet to confirm.
The Cooler master PSU did not come with a LED fan decent PSU strong 12V idles at 12.76V 5v and 3.3v could be better, it was part of a bare bones kit from tiger direct that I ended up with in a trade it's actually in the background in the one pic.

The AS8 is a LGA775 board just ordered a P4 670 to drop in it hopefully it does 250Mhz bus stable all 6 different Prescotts P4s I tried in it ran stable at 250Mhz or higher.

The 7950GT AGP is sadly one of the castrated versions with 20/7 pipelines rather than 24/8 the first one I ordered had 24/8 and 700Mhz memory but the translator chip got cracked due to the sellers poor packing, still very fast with 20/7 at higher clocks in reality overkill for the 875 I put it in originally but 6800GT had a typical demise and didn't want to buy a whole new system. There was a 7950GT AGP made by Axle on ebay week or so ago at $150 that's more than I paid for mine new it didn't take long for it to sell nonetheless I really don't see how this card got such bad reviews when it came out I guess cheap heatsink and no official aftermarket one didn't help it but most people called it trash and a temporary throwaway card until you got a PCI-E system.

Also I forgot to mention that I was running XP SP2 on this build never had any issues running the SuperPi modded

The Prescott 670 will probably not do 19*250 = 4750 Mhz without lots of core voltage and watercooling if you are not really lucky in the chip lottery.

14x300 at stock voltage is a nice 24/7 speed to aim for with basic air cooling, with better cooling and a bit extra voltage 14x333 will give the best performance if the CPU and motherboard can handle it. The 865 chipset often tops out at 300-333 Mhz FSB but 14x321 = 4500 Mhz is faster than 250x19=4750 MHz at least with an Abit AA8XE i925XE board and DDR2. 4750 MHz was borderline stable with a big tower cooler and loads of voltage but stability testing was out of the question because of the heat produced. The same Prescott 670 can do 4500 MHz both at the 14x and at the 19x multiplier without breaking a sweat.

All Prescott 2M should support the 14x multiplier but Im not totally sure how the performance will be with the memory on a 5:4 divider or what ever the board supports.

Yeah 250x19 is pushing it but hoping for a good chip the AS8 is known to run 570/670 P4s at 4750Mhz without modification and usually around 6000Mhz with modification but I do not plan on modding it. The board is most stable at 5:4 divider and doesn't overclock well with CL3 RAM or 4 sticks so 2GB of stable DDR500 is out of the question without an external power source for the memory like the OCZ DDR booster unless some magic low latency 1GB DDR500 sticks exist, may have to get a P4 660 and run it 250x18 to get the optimum performance out of the board

I played the CPU lottery today and won, the 670 P4 I ordered overclocked very well with 1.6885 core voltage set in the BIOS the CPU temp has never gone over 63C and is so far stable at 250x19 and since the PCI clock doesn't have to be pushed higher that 36Mhz to make it stable at 250Mhz bus SATA drives are back on the menu. Can't figure out why this particular 670 has a 12-19 multiplier when they are suppose to have a 14-19 multiplier. The performance is amazing at 4750Mhz will try to make a video soon I have several ways to record S-video. Ran some more benchmarks kept using the modded super PI to keep results comparable

Impressive 😀

Your P4 670 must be a better chip than mine or at least it has alot less "leakage" as my P4 670 would need water cooling to be able to run at 1.6885V without overheating.

When I benched at 4750 MHz I used 1.6V which with v-drop + v-droop in reality was ~1.5 V load and the chip still hit 90C with a Danamics LMX Superleggera tower cooler similar i performance to a Thermalright Ultra-120 Extreme. With your little cooler I would have been stuck at 4.6 Ghz @ 1.45V! 😁

Here is a screenshot showing the spec of my system at the max 100% stable speed using 1.45V set in the BIOS setup, Its not very performance tweaked otherwise with the video card at stock. My card is a 7900 GTX so the memory is clocked higher than on your overclocked 7950GT, I guess thats why my system keeps up with the score you posted in the 3dmark thread. 😀

Very nice!

I must say the P4 model numbers still confuse me, but I really should look into the later models and PCIe chipsets, seems like a fun project.

The Abit AS8 is using the i865PE chipset with AGP but performance wise it holds its own compared to i925XE and it's probably a better choice over all compared to i915 and i925, at least when overclocking.

The screenshot I posted is showing a system with an Abit AA8XE i925XE PCI-E board, it's also from the year 2004 though.

Yea I find higher end AGP cards quite hard to find, so I'd prefer using something newer with PCIe. Also, apparently much newer S775 boards with 30 and 40 series chipsets can still run these chips.

I have used my Gigabyte X48-DS4 to push Netburst chips to the max. 😀

Not all "40 series" motherboards support Netburst chips and the ones who do do not always support them with late BIOS versions. My X48-DS4 supports every non 533 MHz FSB s775 chip in existance with the latest BIOS so I can really recommend the Gigabyte X48 series.

Cool, good to know. I checked out a few boards, some don't take the more power hungry chips also.

I've given up on high end Nvidia based AGP cards but not very many people are taking much interest in good high end DX9 ATI agp cards like the x1950 Pro.

It's funny that people sometimes do that. I guess they think if the electrolyte stays in then the cap hasn't failed.
It's like wrapping duct tape underneath a car to keep the rust from falling out.

I now have a Radeon 3650 for AGP bus. How does that stack up?

3650 = 2600 = 4 ROP's with 8 TMU's and "mind blowing" 120SP's (devide that number by 5, to get real Pixel/Vertex shader number).
So, 3650 has 24 Shaders in total (120/5 = 24), and they can either be PS, VS or GS*.
*DX10 only (Geometry Shader)

X1950 Pro = 12 ROP's + 12 TMU's and 36PS + 8VS

Based on ^that :
X1950 Pro will be faster than 3650 (in games, benchmarks, etc.), BUT it will suck in video playback and Internet browsing (no full hardware acceleration of x264 codecs).

What version of 3650 card U have (guessing it's 256MB, right ?) :
1) (G)DDR2,
2) GDDR3.

Ran into a compatibility problem today with GTA SA with the CPU at 4750Mhz GTA would run way too fast changed the multiplier to 12 and running it a 3000Mhz everything was just fine, so I set the multiplier back to 19 and started turning down the frequency until GTA ran normal 4296Mhz was the highest I could get it to run at a normal speed. Had this happen before on a high clocked 4400Mhz Bulldozer CPU didn't know it was the core clock causing it though.

Not sure what to do now might get some DDR500 to see if there is any increase in performance at 250x19 probably end up putting the 640 back in it to do 250x16 also might get a 650 sometime to do 250x17 that would be ideal. All this talk about putting P4s in newer motherboards makes me want to try this 670 in a 680i motherboard that I have even though it only runs in single channel anymore with the multiplier set at 12 could try for something like 390x12 or 400x12.

Also got brave or stupid considering it is a rare card and it could have made it worthless lump of silicone but I tried flashing the BIOS on the 7950GT AGP with the BIOS from techpowerup.com it has the other pipelines unlocked. Did not work though was corruption on reboot the corruption makes me think the pipelines were unlocked but just not function properly maybe resistors are needed too or maybe it is laser cut like a GS core, rather annoying NVidia and card manufactures went to such lengths to stop you from unlocking the pipelines guess they didn't want people buying the cheaper/older cards and unlocking them like so many did with the 6600 AGP instead of spending the extra on a 6800 AGP

6800 LE to 6800 GT (U can't unlock 6600 GT, since it's based on a different core than 6800 series, but U can OC it to 6600 GT PCI-e level tho 😀).

U were trying to unlock 7950 GT AGP ?
I thought they all have the fully unlocked G71 chips inside...

Good to know. Will check it out when I get a netburst system back in my lab 😀

The card is labelled with 512 MB of DDR2. It's from Amaze.

I found this review of a similar card. It seems to be well ahead of the 6800GT, which is awesome.

MY bad on the 6600 your right been so long since I checked on that. But yes I was trying to unlock the pipelines in G71 A2 core of the 7950GT AGP its supposed to be 24/8 but for some reason there are some like mine with only 20/7 pipelines I really can't figure it out other than maybe they are defects.
