Asus P5W DH Deluxe & 6600 using BIOS OC Safe?

[DSebring]

Ok I just got tired of trying to manual set my RAM correctly so I set startup defaults & then set the OC setting in the BIOS for FSB1333 DDR2 800 and it seems to be working fine!

cpuz shows my RAM CM2X1024-6400C4 running 1:1 at 5.5.5.15 21

VCORE is 1.296 , 1.304, 1.312 (it keeps changing is this bad? )

I see in the DC2 OC guide it recommends 1.425 is this needed?

Anyway I setup Prime to run and then ran Obilvion at the same time for a while and temps were CPU 58C MB 45C - my idle temps are CPU 45C MB 41C.

I have two 40mm fans one on each NB & SB that are keeping the MB temp down

Oh and this is on air, STOCK HS/Fan.

Should I be concerned about any of the voltages?

Cool!


I was really having a time trying to manual set my mem timings with crashes here & there... really frustrating.


I did not even seriously consider that the Asus automatic OC funtions would actually WORK 8O !

Things have really gotten better in the 7 years since I built my last system, back then using any of the Auto options was pretty much the kiss of death if you wanted any kind of stability.

Nice to have something work so well with out much fuss.

Now if I could just get the AMD system I built on an Abit KN9S & 3500+ to be stable I really be in heaven (unfortunatly the ABIT bios on this board is NOT as good as on the Asus IMO)

Just wondering where is this C2D OC guide? looking everywhere ;-)

That doesnt make sense, 1:1 with a 1333 FSB is DDR2-667. Your RAM is DDR2-800 CL4, and to be honest I'd have it running at DDR2-667 CL3 at that FSB. Dont trust what CPU-Z says anyway, I've seen it say Dual Channel with a single DIMM installed, and other helpful things like that.

To get my RAM working right, I just stuck Memtest86+ 1.65 on a CD, and increased one latency at a time, letting it run the first couple of tests each time untill I saw an error. Then I dropped back the latencies a touch and let it run all the way through and it was fine. If your DDR2 800 timings are supposed to be 4-4-4-12, then it should be ok at DDR2-667 at 3-3-3-10, but check the manufaturers website (do NOT trust the specs the store lists)

It needs as little as possible while remaining stable. If it doesnt crash after half an hour with a copy of Prime95 running on each core (two copys is essential as otherwise you only test 1 core. On my D805 core 1 craps out way before Core 0 every time. Set the affinity on each copy to a different core, on the In-Place FFTs probably, go watch TV for a bit) then it is fine.

Anyway I setup Prime to run and then ran Obilvion at the same time for a while and temps were CPU 58C MB 45C - my idle temps are CPU 45C MB 41C.

Not tooo bad, but leave Rightmark CPU Clock running with Prime95, and make sure the CPU isnt thermal throttling on either core.
