Cache not working at 133fsb?

The data sheet says the clock synthesizer can go up to 150 MHz . But, I can’t set 140 and above. I can only set what is below bios settings and back . Bios can select up to 133 . The cache module was replaced from 512k to 1M, but I can’t figure out how to make it work. It detects 1024 but can’t go further than a summary screen with cache on at any frequency. I think I have enough skill to add 140 and 150 MHz options in bios. They go through I2C bus.

You can try lowering the timings on the cache. I was only able to get my 4ns 2Mb cache on my freeway board to run around 124fsb

What score dou you have in 5k challenge with your freeway mobo with 2 megs of 124Mhz cache ? I had 5000+ with 1 meg of 124Mhz cache @ 624 MHz of K6-3+ . Now I have new setup and I’m trying to go cacheless with 133+ FSB , since my new mobo had only 512k cache in stock and I just swapped cache with 1024k module without messing with cache-setting resistors. And it does not work yet with cache on.

I got same videos. To load them properly you must overclock pci bus. My 7500 DDR PCI have shown 6600 pts using CUSL2-c with Celeron 1000@1700+, while Barton @ 2000+ MHz and NForce2 was able to show only 6200 in 3dmark2k. Win98. GF2MX may have chance to boost via lightweight driver, but PCI cuts the performance @ 33 MHz significantly.
GF2 Mx400: 6000+ points @AGP
Radeon 7500 DDR / 9200: ~ 9000+ points @ AGP

Ultra Freeway. I remember now. Your system has potential to hit 5500 with proper cpu with all that cache at 124.

Windows 98SE with 7.76

Interesting I wonder if ME is the issue.

I’ve finally managed to swap the cache on my P5A 1.06 mobo from 512k to 1mb. However, I’m facing stability issues and I just can’t get my tests complete yet. Maybe full recap is needed. It cannot run stable at 124 MHz , but it did earlier. Maybe tag SRAM IC must be replaced to a more agile one.

Very nice!

Isn’t there a thread around here for how to do that? Did you document the process?

i just used a photo from Skalabala (thanks!) to do the mod. I left a post in that nearby thread. There was a ceramic capacitor C78 near the cache chip that greatly impacted the stability. It was not populated in other 1.06 and 1.04 and my P5A-B with TAG IC. So I removed it and my memory banks were counted correctly. Maybe it was just a “leaky” cap.

That is awesome 😁
I could only run at 120MHz, 124MHz made my hard drive crash I think. Is it stable at 120x5.5?

My VIA Tekram runs @ 133 and hdd never crashes . My P5A mobo is unstable at 110 and above . It crashes-reboots and it can’t go over 600. I think I can improve stability by recapping. 124 MHz loads Win98 and Sandra and there’s is hope) going to test my King Shaman 2 (Voodoo2 SLI).

I finally recapped and installed ceramic capacitor shunts in my Asus P5A v 1.06 with 1mb of cache, K6 plus mod. The 1meg of cache I installed recently (see above) by adding tag sram IC and two resistors R33 and R35 of 33 Ohm.
It runs 5000+ pts at 617 MHz (112x5.5) with cache on @ 2.5v . Unfortunately , it does not take with cache @115 at all. I need to search for a faster tag sram, since I swapped this IC from the baby brother P5A-B. I use Abit Siluro GF3Ti128 mb @ almost Ti500 frequencies. I think the mobo suffers from some performance loss due to k6 plus problem in rev 1.0.6. It shows only 200 mb/s memory transfer rate due to Sandra 2k. The CPU can run at 676 MHz for a couple of secs, though)) however , it will not help since 6x multiplier actually slows down the performance.

I have posted somewhere in this thread a link to 6.5ns tag ram.
I am now trying a 1.06 P5AB and thus far I am at 4600 with 617mhz K6-2+ 2.2V. Can run 2.2V 633mhz cache off.
It wont run 115mhz with cache on 🤣.
Looking back at my score of 5700... Damn that was hard but soo worth it!
I am working towards turbo pll in the future.
Also trying a Matsonic MS6260S with 1Mb cache, seems to be slow.
BTW I gained 80 points going from 128mb to 256mb ram! 🤣!

Damn you're getting epic scores... My system:

-Soyo 5EMA+ V1.1
-1MB cache
-K6-III+ @620MHz (112x5.5)
-Geforce 2 GTS
-256MB RAM (1 stick)
-Voodoo 2
-Aureal Vortex 2
-Orpheus II
-32GB MicroSD as HDD
-Windows 98SE with Unofficial SP3
-Directx9 from the SP3

Everything is set tightest in BIOS and after I tweak AGP settings with Tweakbios (finnish software) I get around ~4100 points in 3DMark2000.
Detonator 7.76 is used.

Is VIA just soo much slower than ALI?

Had many Asus P5A v1.06 -boards some time ago but all were unstable, random reboots when just idling in windows desktop. Maybe those needed recapping but never had the time to do that. And top of that those needed the little mod to get K6-2+/3+models going.

The VIA boards are slightly slower. But there is a chance they might catch up in some games.
4100 is not bad but there is some hidden points left for you.

Turn USB off, use wpcrset tweaks I posted somewhere in the thread to maximize performance and you will be around 4800-4900. GF2 Ultra I think can hit 5k, need to check , I have one. I used to hit 5k with GF3 and a setup similar to yours. That’s true if your mobo can run 124MHz with cache on. 1mb of cache makes around 10% gain in score. Every 512k gives around 5%.

I had one of those boards, and I found that my Epox MVP3G-M is slightly faster. But I also found that Direct X 9 slightly lowered my score, and my experience with the "service pack" wasn't good, so I'll never use that again. If you aren't already using it, the Breese memory interleave patch will give you a small boost in memory performance. I would remove the sound card for benchmarking. My best score was 4,500.
