MSI Neo4 Platinum 1B bios Cant overclock or start with 133Mhz Ram speed.

[imported_Kingnubian]

Does anyone else have this issue. I'm using an MSI Neo4 Platinum (non-sli) with an Opteron 165 and the 1B bios (Dual core aware bios). Setting my ram speed to 133Mhz (266DDR) and overclockin even a little results in the pc locking up at boot!! It runs 100% right now at 250Ht, ram at 166Mhz (414 effective with raised htt) and 4x Ht divider. Simply setting the ram speed to 133Mhz results in a non booting system

Any clues how to get my 133Mhz setting to work? Any workarounds which won't comprimise the bios recognizing the dual core chip properly????

more info please.

what ram are you using?

also are you setting a mem divider? cuz i can't figure out if you are.

you say ram speed 133

and then say later ram at 166

so...

yeah...

but first more info on your ram is needed

manufacturer, rated speed, timings, voltage

I apoligize for being vague. This is my system and a description of the problem.


MSI K8N Neo4 Platinum (Bios 1b)
Opteron 165 (default voltage)
1gig (2x512MB Dual Channel) Platinum Memory (Reported as PDP Systems by CPU-Z)
Seagate 80gig 7200.7 Hard Drive
Liteon DVD-rom drive
BenQ 16x DVDr
ATI 2meg Rage Pro PCI (!!!)
SilenX 400W PSU
Artic Cooling Freezer 64 Pro CPU Heatsink/Fan

I have this strange problem. reduced my HTT multiplier to 4x, and set FSB to 250Mhz with Ram at 166MHz(333Mhz ddr to keep ram from being a limiting point). Using Nvidia Monitor Cpu speed is now reported as as 2250Mhz (stock voltage), ram 415Mhz effective, and HT at 1Ghz. At this point the system is 100% stable.

My ram will not do much more than it is right now, at least not without playing with timings which I'm not skilled at yet. I then reduced my ram speed to 133Mhz (266Mhz ddr) to try and push my cpu speed (FSB) higher while reducing my HTT multiplier to 3x so it wouldn't be an issue in the overclock.

Seems even if I leave everything alone, setting my ram to 133Mhz results in a system that won't boot!!! Now this is strange. Even without moving any other setting and just dropping my ram speed form 166Mhz(ddr 333) to 133Mhz(ddr 266) results in no joy. Setting it back to 166Mhz results in a stable system once again. Increasing voltage of the dimms or cpu doesn't seem to help.

I am presently using a cheap ATI Rage Pro PCI card untill my more beefy x800GTO2 (Unlocked and overclocked to PE speeds 100% stable) comes in.

What could be wrong??? Is there an issue with the 1b bios release possibly and ram speed settings below ddr 333 while overclocking??

that could be a possibilty. i do not own that board nor have experience with it.

maybe someone with that board could chime in.

but might be a bios problem like you said.

I remember having a problem with that bios when I was setting up my sons NEO4 with an Opty 146...It booted slow, couldn't change the command rate and would just die at POST.

I have finally setteled on 1.9 and everything is fine now, although I don't have a DC. The point I'm trying to make is that I had issues with that bios also.

Solved the problem. Had to enter in my ram timing values manually. Seeems the bios may be defaulting to values that are too tight when setting the ram divider to 133. Set it to 2.5-3-3-6 1T and all is well. Now I'm at 270 FSB and soon going higher.
