Competition page needs fix. This was pifast sub.

Waiting it.

will you take part in comp?

good. Re-capped the only via-based board I have (VH6-II) and should be ready this week for 2D.

Well, i still have 4 other submissions to prepare:) @all let's not sandbug this time?) The platform is not very popular so if we share our results in good time we may all know smth new and get results stronger than expected.

Anyone has an issue with cmos clear? No matter what (clrcmos button on the back panel, clrcms switch), board keeps settings.

These cpus are quite easy - the edge of stability for these is quite easy to find so once you will find it you can make video. It is very unlikely you can get result beyond that edge to have multiple attempts to record video. @GRIFF, suggestion. Would it be possible to change 9100 to 9550 or 9200/9250 (which are almost 10 times more popular)? We have only 125 subs with 9100 @hwbot, which indicates 9100 is relatevely rare card. Anyway, most likely I won't be benching 3d even if 9550 is allowed but that may become an entry ticket for many other ocers.

Nice score, friend!

Let's see if it works first. I don't forsee problems making video

What are requirements for video? What should be there - one presses run, camera then flows to show mobo and thermometer and then back to the display to see the result?

Strong score!

Are these final requirements (actually comp page shows coppermine 128/256 and no cooling requirement)? I mean, air (>10C) and 66-mhz coppermine cpu?

Thanks. Is it possible to use non-rad3on card for 2d stages? I don't have 9100 and it is not available for sale. PS. I'm not really sure if i have VIA board though to take part. Good luck all.

What are the benchmarks? Can't see them. What is the timeline?

Well done. Try adjusting skews first - cpu skew of 200-300ps and nb of 0-100ps when running high fsb.

Not sure if it ever existed except some engineering samples. I had only ECS P6S5AT with sis635t and even with PLLmod the experience was not that successful - I think sis635t must be very picky with RAM (same as pro266 - I had only one ddr stick able to work @195mhz or so - and it was micron 5b not bh5) and won't go >200mhz RAM tight (and as the cpu bus is 64bit, the only advantage of ddr chipsets is to beat i815 with ram frequency). I would better then investigate i820/i840 and RDRAM - if these would go 250mhz fsb-wise then there may be a chance (but not for every cpu etс). But again, never seen interesting boards for sale (and intel boards lack proper clock generators).

That is the same pcb with some bells&whistles missing - agp instead agp-pro, no cnr, no integrated vga. Never tried it though. Should be identical to CUSL2 in terms of overclocking.

That could be a dram vrm bug of a partucular board to kill it - not a platform issue. I had s478 board recently with pll mod that was accidentally killing cpus although pll voltage was in line with no-mod boards.

Dead sure this is the same card as here - https://hwbot.org/submission/4083883_ Most likely, cheat involves nvstrap driver. Same bios, same score, same clocks

I had several mobos on i815 with integrated video and they were no go for overclocking. However I was quite noobie that days so don't know what to expect with proper approach. Video is last thing one should consider with this socket anyway.

External clock may have less jitter/phase noise (i.e. high end audiophile gear sometimes use external clocks for their DAC of a femtosecond grade). That is my guess. At least, the different quality of pll ic may be the reason why TUSL/CUSL boards have certain difference in max clock between samples - the reason may be not chipset but pll. GraduS should know more - he was really deep into digging JP forums on s370.

Those were turboPLL/JordanPLL to allow overclocking on the boards with no-overclock stock pll ic. I believe you cannot run pci/ide in asynchronous mode if chipset doesn't support it which is the case for i815

Easiest way to check what limits you is to use different "straps" and low multi coppermine d0. First check fsb limit of cpu with 133/100 and write down clocks for pci (if waza locks system at given fsb - then it is ide limit). Then go 133/133 to find memory limit. Then check 66/100 to see if you can break the pci clocks of 133/100 while staying with dram below limit of 133/133. PS. IDE is definitely a problem. Japanese were using IBM fireballs if i'm not mistaken in early 00's which were known to stand 50-55 mhz ide clocks.

Why have temperature restrictions if we only have 4.5GHz limit? More to that, I guess monitoring software like HWINFO should (must) have a possibility to offset the values so it will be easy to trick it. Another trick is - run the test with eg. SS, run the test, open tabs, switch SS off and let the temperature rise. I think temperature limit should be removed and the frequency limit should be adjusted to meet "average air overclock" for the given DIV#X platforms. Let's say, if the stage assumes the use of Pentium III Coppermine, let the LCC frequency be 1200MHz or 3600MHz for Core 65nm.

I have also bought one yesterday. It is 620 fsb stable 1:1 but won't go higher than 1600 dram no matter what. Will sell it asap.
