I will once I have time to to run a bunch of different tests. I did actually look at some 780Ti 2x vs 3x vs 4x benchmarks and there are some games that show significant improvements with 3x and 4x.

I always liked the idea of SLI (and CrossFire) in theory, but I never went for it due to the infamous micro stutter problems that many people experience when using such a setup.

Let us know if you run into anything like that on your 4x SLI rig.I'm curious to see how that turns out.

I know that AMD fixed the microstutter for the most part.. at least on the 7970 and up as I had that setup for a while before they fixed it and after they fixed it.

I still have one of the 7970 cards and kinda wish I still had the second.

That reminds me.. I also have 2x HD6870.

i have only one experience with SLI and it was a good experience - i bought an i5 2500k and a gtx 570 for battlefield 3 in 2011, then 2 weeks later I decided 70fps wasn't good enough so i bought another gtx 570. no problems whatsoever (with bf3 in SLI, i didnt really play much else). i got an extra 40-50fps out of it so it, was a great improvement at the time. i still have all the parts, maybe it's time to resurrect the build... is SLI supported in WinXP? 🤣

Tell me I'm not insane.. I just bought 4x GTX 780Ti. anybody ever tried 4-way SLI in XP? I have a board (ASUS Rampage V Extreme) that can do it along with a XEON E5-1660 V3 (octa-core) that overclocks to 4.5Ghz which is going to probably be the upgrade to my current main system but not with this particular motherboard.

Just curious, how much did you pay for these 780Ti's, and what model was it ?

And, how easy would it be to install a stress free and fully workable WindowsXP on that X99 motherboard ?
(have you succeded already perhaps? 😮)

Very nice haul! Amazing the amount of boxed stuff 👍

Thanks. The motherboards (386,486) are mostly new. Just spent an evening clipping away the batteries. Good thing that they were stacked horizontally rather than vertically as the acid hadn't spread from the battery ends. I'll post more detailed pics next week of the complete haul as I still have another pickup for the rest of the stuff (like the monitors) after Christmas. A lot of Commodore/Spectrum literature too.

Some HD photos would be very useful for documenting these boards.

Have bought a couple of NOS zida 4dps for 8 us dollars each, those board are pretty common on local flea market.

This week I received a nice dual-GPU addition to my graphics cards collection: A Gainward Radeon HD 4870 X2.
I bought it off eBay from a seller with a bad rating and bundled together with a badly beaten R9 270X. In the photos you could see that it was missing the X-shaped GPU cooler mounts on the back and some screws, so I wasn't too optimistic. But the price was low enough (paid 6.50€ + shipping) to give it a try.
It turned out that the R9 was indeed dead. So I went on with the 4870 X2, opened it up, cleaned up the mess that the previous owner had made with the thermal pads and paste, applied some new paste and secured the heatsinks as good as possible for a quick test.
Fired it up in my S775 system and, YEAH!, it does POST 😄
I didn't want to make any further tests without properly securing the heatsinks, so now I'll have to try to find the matching X-shaped cooler mounts and screws, or a proper aftermarket cooler (Accelero Xtreme 4870X2).

They are EVGA - blower style. Listed on eBay for $89.99. Offered $70 a piece and was accepted.

Should be pretty easy to run XP.. planning on using x64.

Today, this thing arrived.. It came without the power supply but for 35 euros it's still a good deal I think.

Are you sure it has a VRM ? I thought the only slotket with a VRM was the PowerLeap one . AFAIK, all the other slotkets only allow overriding the CPU VID presented to the motherboard's VRM circuit .

Does an ABIT slotket III have a VRM

This says it have same chip as on powerleaps https://translate.google.com/translate?sl=aut … s/tbx/tbx_2.htm

AFAIK, the ABIT slotket III does not have a VRM . The chip you are referring to is a TVC16222 or TVC16222A , which, as far as I know, is used for I/O voltage conversion . Again, AFAIK, the supply voltage for the CPU is fed directly from the motherboard's VRM circuit on all slotket variants I know of, except the Powerleap PL-IP3/T, which has it's own VRM circuit (which is fed through a direct connection from the PSU) .

I am not an expert at this, so If somebody here knows more about this and/or if I got something wrong, please feel free to supplement/correct me .

I received the AOpen FC-PGA yesterday. It has a chip for I/O voltage conversion as well (Texas Instruments SN74TVC3010, or SN74TVC3010PWR to be precise) but no CPU VRM. Works fine with a 1000/100 CuMine on my Diamond Micronics C400. Most adapters with an I/O voltage conversion chip seem to support the Tualatin mod, so I went ahead and ordered two PCB-style adapters on eBay. One will go onto a 1400/100 Tualatin Celeron and the other one onto a 1400/133 PIII-S. So I can fiddle around with the C400 and my Epox EP-BX3 (which supports 133 MHz FSB).

What kind of adapters are these, you put them on a slotket, between cpu and it ?
Item number ? 😅

Thanks for taking the time to ID my boards, I really appreciate it. The last one (430BX socket 7) is a QDI TITANIUM I B+

You have to permanently attach it to the CPU by de-soldering some pins and soldering the PCB to some other pins. Search for eBay seller "user8012". He sells the loose PCBs as well as already modded CPUs. I think there are a few people here who are successfully using these modded CPUs.
Of course you also need a motherboard that supports the lower CPU voltage and has a modded BIOS with the Tualatin microcode updates installed. For 133 MHz FSB CPUs you will obviously need a suitable motherboard, too. Many 440BX boards support 66/100 MHz FSB only.

Decided to get this Biostar MB-1500PCT motherboard and try to restore it. Kind of above my skillset, but I really want a Pentium/VLB board, and can't really find one for adequate money.

So far I can see the following things missing:

- cache chips;
- CMOS battery;
- BIOS chip;
- two VRM modules;
- an unknown DIP14 chip between the second and the third ISA slots.

I'll probably make a dedicated thread asking for assistance, but in the meantime maybe someone has this board and could make pictures of the missing elements?

I have never seen VIP board with socket 5 😮 I hope restoration will be successful 😉

Still restoring my $20 SuperMicro P54VL-PCI board. Glad to see another Socket 5 board with VLB.

Got myself some treatments.
I recall Micronics mobos were horribly expensive but well built in general.
This one isn't exception; well thought-out layout, good components everywhere, easy jumper labels, and so on.

There's one glitch though.
Once you hook an ATX power plug, it's pretty fucking annoying to pull it out due to a capacitor not letting go of the plug's notch.
I had to cut the notch off at the end. 😐

Awesome. Never seen one myself.
Hope these get you started.

MB-1500PCT Full Shot
MB-1500PCT Cache

While I've been in Poland I've bought these PC cases. These are brand new! Our local shop "ProLine" put huge discount on some "outdated" products. These are brand new, packed in an original cartoon package. I'm stunned.
The price for 4 PC cases was ~ 47 USD.

Picked up this 1.1ghz 100fsb PIII. Small nick on the side of the cpu but it works fine. Nice chip for a BX system.

Wow. Nice to see that people are restoring their Pentium VLB systems.

This one is my recently acquired board. Still working on it. Need to solder missing voltage regulator.
