Opty 148 stuck at 267x11

[primuslesler]

Ok i have an opteron 148 CAB2E and i cant get it past 2.937Ghz

I have the RAM at DDR266 and 2.8V 2.5-4-4-8
The CPU is 267x11 at 1.8V
HTT multiplier is 3x

I'm not sure what else to do to get a higher clock i was hoping for at least 3.0ghz but i would need 273x11 to obtain that

Sometimes you just hit a wall, no matter how much you want it you can't have it!!! You could try lowering the ram even more, and going with 300x10.... it's worth a shot!

do you think my voltage is to high for CPU for Air cooling? because everyones in http://www.ocforums.com/showthread.php?t=427461 is much lower than 2.8

um yeah dont run 1.8V.. you risk killing that CPU awefully quickly. youve followed the instructions on that thread about burning in? if so, then you could try using a different multi/htt combination, and if all that fails, then chances are youve hit a wall with your current cooling.

im doing CPUburn now and CPUstress

with both running my temps are at 45C and everything is at Stock right now

im not sure which options to use for CPUburn ive never used it before

man, 1.8v on air... you're crazy what are you using for cooling right now? if you're on stock, then 2.9Ghz is pretty good for stock cooling IMO. i would suggest getting a new hs/f if you're hitting 45c load @ stock speeds. that seems a lil high to me, unless you're on stock then that would be about right.

 

[primuslesler]

Yep im on stock... figured it would be a waste to buy a good after market heatsink when im getting watercooling hopefully soon after my B-Day. i have $60 from a lottery ticket i found on the ground and I'm guessing about $100 for my B-Day from friends

 

[penixor]

160$ isnt much when it comes to a nice water cooling set up, good setups cost about 200-260$ depending on how nice yours is going to be.

 

[ziggo0]

Your gonna own that CPU with 1.8v...most people agree on 1.6v as a max on air...good luck.

 

[Careface]

yeah i hope you change it soon really, 1.8V on water is still pushing it.. but 1.8V on stock air? Youre -ASKING- for it to die lol. Im usually pretty relaxed about safe voltages, ill regularily put more voltage than i should, but really 1.8V and dual core on stock cooling? Uggh, you live dangerously lol

[primuslesler]

well i was hesitant to even up the voltage with stock air and a friend from OCF said 1.8V would be perfectly fine and i gave in and did it... don't worry it wasnt at 1.8V for more than a minute because it wouldnt post at 268 so i cleared CMOS and got lazy for the night and played some WarRock

 

[Spion]

i'm guessin they meant 1.8v for socket A chips. its a good thing it wasn't at 1.8v for too long, otherwise you probly would've had a dead chip. but anyways, good luck at getting 3GHz out of that chip. just make sure you keeps your voltage at a reasonable level lol

160 is great for water... nice big hc 30$ whitewater 40 pump 70 tubeing 10 dam near top of the line

The ram is ddr266 or ddr333 (pc3200)???

The ram is ddr266 or ddr333 (pc3200)???

he means its on a 266 dividor (at least thats what i'm assuming). so the memory is running 2/3 of what the HTT is set at. so his memory would be running at 267*2/3*2(ddr) so he is running at ~ ddr356 speeds. ddr333 is pc2700 speeds, ddr400 is pc3200

he is correct i dont know the ratios for dividers so i just put 266
