PIII 600@800 on Trinity 400 but not on P3V4!

[Moving Target]

I have had my PIII600@800 running very stable on my Trinity 400 @ 1.65v for a while now, so I wanted more and got the P3V4. Know it won't run @800, even at 1.85v, it boots into windows, but is very unstable.

Any Ideas?

The only thing that changed was the MOBO.

System:
PIII600E
Abit SlotKET III
128MB PC100 (ran @133 on trinity, know @100 on P3V4)
GeForce 256 with 6.18 drivers
WD 10G ATA66
SoundBlaster PCI512
Linksys 10/100
ASUS 50X CD-Rom

Come on, none of you have an idea!

Any help would be great!

Hey dude...

well not sure what the problem may be... I have tried the same CPU on many different boards with completely different success stories for each. I mean the thing that hit me was the difference that RAM made and by that I don't mean the quality but just pulling one of me dimms out and wham.. everything would be stable again. Some boards handle RAM (types, amount) better than others. All I know for sure is that I have an ABIT BX6-r2 board and I bought a brand new ABIT board that supported 133 BUS and AGP 4 and UDMA 66 and it was only stable at 450 (my original CPU p3). On the BX board I could get it close to 600 no prob. Then again my friend could not OC his P3-500 past the turbo option on ANY board... it is so picky.. humm not sure. For one thing.. I would drop that Linksys card.. trust me
i actually figured out that network card was screwing things up on any chipset other than a BX. Got a 3Com and wham.. all was stable again and could overclock once again. The DDR was not a prob.. have the same and makes no difference. You have PC-100 RAM.. that could be an issue but if it worked on the older board... hummm.. Try pulling everything out.. leave just the VC, the RAM (of course) and the HD and see if it boots.. then add components at will... again drop the Linksys

Good luck

The P3V4X is pickier than BX boards. The PC-100 ram may not cut it at 124 Mhz on the P3V4X.

Are you setting the ram timings to SPD or setting them manually?

The ABIT sloket III may be contributing to some of the problems. Many people have said their problems went away when they switched to an Asus Smartcard converter. Again, the P3V4X seems to be more choosy about what it wants. I have a couple of Abit SloketIII cards running on BX boards, including a P3B-F...but my three P3V4X boards all use Asus converters. All are using PIII-650's, all running at 866 Mhz with PC-133 ram and set to 1.75v.

Removed Network and sound cards, still no go. I'm trying a diff adapter card tonite.

Any other ideas?

Well, I use the Abit!!! and it works great for me. I really do not have any ideas except wondering why you changed mobo's in the first place? A 600e@800 with default voltage on a BX board and you weren't happy? Even if you got the 600e to 840 or 850 on the P3V4 (about the 600's limit with air cooling), the 600@800/BX is still a faster system.

Return that P3V4 and be happy with what you had.

Got the ASUS SmartCard and running at 800@1.65 volts, so far very stable. Been looping 3DMarks for about 1.5 HRS now without missing a beat!

The Trinity IS a VIA chipset, not BX. And in 3Dmarks2000 I was getting 4150 3DMarks on the Trinity, now on the P3V4 I am getting 4560 3DMarks.

Looks like the Asus Smartcard is definitely the way to go with the P3V4X. Good deal on getting stable.

I see, thanks for the correction.
