Dual PIII 850E W/ Abit VP6 Overclocking

[NDC]

Just curious if any members here are running a Dual PIII 850E on an ABit VP6 mainboard. What's the highest you were able to overclock this chip on this mainboard with this particular processor.

Please post Core Voltage, VCC3 Voltage, and Divider setting...

I can't really help you on this one but I would advise against any abit mainboard sue to their low quality. I am sure you prefer Tyan yourself.

Good luck.

You've had bad luck with Abit I take it, Otheos. Actually this is my 3rd Abit mainboard I've purchased. A VP6 Dual P3 850Mhz @ 940Mhz, Abit BE6-II Celeron 700Mhz @ 945Mhz, and Abit KT7A AMD T-Bird 1Ghz @ 1.4Ghz. All three of these systems are running rock stable without giving me any problems up to this day. What makes you say that Abit produces low-quality mainboards?


As for opinion on Tyan dual mainboards, YES, they make excellent dual mainboards! I was very happy with the Tyan S1832-DL mainboard. That is most stable dual mainboard I've used yet (OC'ed or not). I still build workstations and servers using Tyan Dual mainboards. Tyan has a more of a reputation for Multi-Processor Mainboards Vs. Uni-Processor boards...

We're going off topic here but I have to support my comment on Abit. Abit has the highest number of RMA's out of all motherboard manufacturers in the end user market (Abit does not do OEM and it's share in the end user ONLY, is quite high). The number of RMA per number of sold motherboards (i.e. normalised) is almost double that of the next (PCChips) manufacturer.

Abit being a small company has not a high standard quality control dept. Add to that the max performance tuning and their product are more susceptible to faults than others.

I have (and to the day still have) owned abit motherboards with no problems, only to find out that ALL (ok that's bad luck) the people I have recommended to buy abit had to RMA it at least once. (The figures above are from the 8 largest European retailers not my experience http://www.sysopt.com/forum/smile.gif)

WOW! Thanks for the great info, Otheos! I never knew about this until you mentioned it. I must be very lucky then... I haven't had a single problem with any of my ABIT mainboards, THANK GOD! Nothing could be worse than coming home to assemble your new system and you find out that a part is defective! I've had that happen before and it can really **** someone off!

I just finished building my Twin 1Ghz; 80GB RAID 0 machine on a Abit VP6. To back up what otheos is saying about Abit, this is my 3rd VP6!! But this board is very good when it's running properly!

I would like to O/C these, I jsut don't know what the optimal non damaging temp. is to aim for or stay below.

Just off curiosity, what was defective on the first two VP6's?

[Acid Burn99]

The first one, during the install a mobo riser was preinstalled by the case manufacturer and not removed prior to the install, frying the board. It would check the keyboard then stopped when it went to allocate/check RAM. The second one had BIOS issues, and wouldn't boot.

Can't directly comment on o/c potential with the VP6, but two P3 800e cb0's can run perfectly fine at 1+ GHz on my cheap ECS D6VAA with no prob. Thought I would offer some comparison, especially considering this is a $75 board.

I have a feeling that the P3 850E chips aren't very OC'able... What do you think, Rob?

[krusty the klown]

Hmmm.... well with an 850, the 'sweet spot' in terms of FSB is going to be 1130MHz & 133MHz FSB. I think 1130 is optimistic, as Intel couldn't get the things to run right at this speed.

If you don't mind 'odd' FSBs, then the 850 chips might be 'failed' 1130 CPUs... in which case, they could have a good chance of hitting somewhere around the GHz mark. Bit of speculation here... but notice how the faster MHz Intel chips seem to run at a higher voltage (for the same stepping)... and what do we OCers do to get more MHz? http://www.sysopt.com/forum/wink.gif

I'm quite happy with my VP6 and 2 700E CC0s at 933. It is very OC friendly with the 1MHz FSB increments and VIO adjustment, but my only gripe is that the board will not let you adjust the core voltages independently - I'm probably giving one chip a little too much juice and you really only want to give them what they need - no more!
