Yesterday, I finally decided to go with the mod for the best CPU (#3) in the batch. After de-lidding, some cleaning (btw. plastic eraser is great for scrubbing the remnants of TIM from CPU) and de/re-soldering of the link (here I am not sure if it's a 0 Ohm link or a capacitor because my measurement …

First a little teaser: SSTIMG09.PNG Then a full story: About a month ago, a batch of three AMD K6-2+ 570 MHz (570ACZ) from a well known seller finally arrived. I prepared my trusty Gigabyte GA-5AA (cache stable at 115 MHz FSB), nice cooler with a copper core and began. First I quickly confirmed that …

I can also confirm that VIA C3 1.2A runs on CUBX-E with the latest 1008cul004_20220218 without serious problems. As mentioned, temperature reading is wrong, but this is not an issue for me. Thanks for the mod, this will make a very interesting retro machine. Filename cpuz.png File size 15.42 KiB …

I had similar issues with MSI 694T Pro. ISA slot was populated with ESS AudioDrive ES1869F (BTC 1857A) and I had huge problems with my Gotek. Floppy emulator was detected, but file transfers were corrupted and usually ending with errors and broken file system. I tried everything, first suspecting …

OK, complete success! Testing CPU was Intel Celeron 900 MHz SL633 (default voltage) on aforementioned QDI P6V694T/A10T with ICS94241. I was able to get FSB and of course set it. Lowest supported frequency was in my case 90 MHz, highest 120 MHz. Utility works even with EMM386 and can also be used in …

I will try to test the utility on my QDI P6V694T/A10T with ICS942 4 1. This PLL looks very similar to already supported ICS94211. I was trying to compare datasheets, but I don't know what to look for: https://digchip.com/datasheets/parts/datasheet/212/ICS94241-pdf.php It would be a huge help if this …

Thanks for the tip, CPUFSB (tested version 2.2.18) supports also ICS94241 on my version of the board. Unfortunately CPUFSB cannot be registered anymore, so it's quite difficult to work with it.

Late to the party, but if someone else will stumble upon this I can confirm that the reason for different OC capability is indeed clock generator. Recently I have acquired this board and it has the ICS94241, whereas the production began with Cypress clockgen originally. This board was also …

Yes, I suppose... But wouldn't the P4-M 2.0 be a better choice with the 20x multiplier (20 x 133 = 2660)... What FSB are you running at to get to 2.6? 110? How does that work with Vanilla Brookdale (i845), is the FSB independent of the AGP/PCI divider? As was discussed, with P4-M 2.0 you are stuck …

Unfortunately this falconsoft's SSTEP 1.0 doesn't work either. As mockingbird wrote, it's probably some physical incompatibility with desktop boards for these early speedstep CPUs. In any case the main advantage of Mobile P4 is power consumption. This SL789 I have is quite exotic - it's a hybrid …

Seeing as how the multiplier-unlocked engineering samples and extreme editions are unobtanium, a VIA + P4 combination seems the best choice for CPU throttling. With throttle, you get 16 different speed reduction options with VIA chipsets, plus the ability via switch to not toggle the L1 (so 32 …

Exactly, lower price is one of the main points for this potential version, apart from smaller size (although I'm not sure if there are any problems in this regard with current X2, maybe it already fits on every sound card with waveblaster header).

What I meant is the exact opposite - more stripped down version of current X2GS, without USB, only 16mbyte read only GS, no line out and no preset editor. Something as simple as former Yucatan Fx.

To my eyes, these look more like over-sharpening artefacts . I presume you've already tried auto-config to no avail . Have you tried lowering the sharpness setting ? Also, If that AOC monitor displays correctly when fed through DVI or HDMI, you might want to consider an external digital like an …

Sharpness setting is something definitely worth checking out. Although as I have experienced in the past, the effect of oversharpening was much more subtle (more like a corona around objects). The effect in the picture is huge (several pixels) and the shadows are going strictly in horizontal …
