Sorry, but I don't see that being stable at any higher vcore on air.

i still feel blazin's problem is memory, not the cpu.

either that or he got a bunk CCBBE, which i doubt.

@compgeek, that was a quick sell on ur processor. i can't believe no one wants mine :(

can't point you to a review, but I can tell you my A8N32-SLi does 334 with ease. Tops out at 349 exactly, 350 no setting change makes a difference.

Ok get a hold of this... My 0609FPBW does 2750Mhz on stock volts Prime, Rosetta, whatever I throw at it. That's 950Mhz OC on stock volts.

But, 2.8 needs 1.4v already and above it gets only worse. 2.9 needs around 1.525v and 3.0 hasnt been stable at any setting (tried upto 1.6v).

Does this thing scale horribly or what, temps can't be the problem as they never get above ~45C in a warm room with dual Rosetta running. Mem is on lowest divider on timings I know it to be stable at 270Mhz. LDT and chipset volts are up and multi's are set.

Whats going on?

so it scales normally...

2750 1.35
2850 1.45
2950 1.55

100mhz/.1v
just like most 165's

They always scale like that

.1v/100Mhz.. yours almost follows that, just needs a slight bump for the last 100Mhz

edit: he beat me

yea, most start to struggle a little bit at the top of the vcore line, so the jump from 1.45 to 1.55 might only get you like 80-90mhz. the stronger chips hold firm to 100mhz/.1v

hmm...

pc in basement + central air = low ambient temp

full load temp is 40c @ 1.475v.

i just dont get it. ive been scouring the web for HZ settings that will make this thing faster. im hoping im not the only one with a dud CCBBE. if thats the case.....i will sell all and prepare for conroe, lol.

Great to know! my chip falls right in the norm. then my volts are just slightly I can reach 2750 @ 1.33v but 2.8 does not come @ 1.4v (as far as I can see) but I might of reached a themal barrier though... I think someone hit it right on the nail when they said 55c = instability.

Seriously.. just sell it for $300 and move on, buy another for $275. If mine don't do 2.9@1.35 I immediately label them for the selling :p: Think my standards may be a little high though

temp instabililty will vary from chip to chip. mine will run fine at 58c, it fails around 60-62c.

hiya mate i have the same steepping chip mine is prime stable at 1.37 volt at 2990 , i am currently running at 3107 @1.47 all the time not prime stable art that though but done 3dmark06 at 3030 ok, not much info on this stepping but i think they are a decent one, i found on the ram max async latency at 9 help , very pleased with mine

yes. your standards are high. :p:

@ blazin, the SS i posted is optimized settings for 300+ HTT on G.Skill F1-4000USU2-2GBHZ

3107 @ 1.47? on what cooling?

I have same mem as you, i couldnt get my 0610 above 2.8, i had given up really as I had lowered my mem speed on a divider so low to get it out of the equation as people say to do. I then thought sod it and ran my mem on a 150 divider and hey presto it went upto 2920 at 1.475v.

i have since found the same thing with my 0608, craps out around 2.85 with 133 or lower divider but i can squeeze 3.0GHz with 150 divider.

Weird! Worth a try though.

200 Mhz memclock ? isnt that high for a 300+ HTT ?

mmm... no

thats a 2/3 divider at 300HTT, any higher HTT you will possibly need to use 1/2 divider

My HZ is set to 150 divider in bios so runs at 300 / 200 * 150 = 225

It also shows as 150 in A64, so I would asume 300 / 200 * 200 = 300 ?
06-06-2006, 01:10 PM

egh?

its a 2/3 (133) divider, so at 300HTT it runs at 200mhz. yes? i'm not really following your calculations there....
06-06-2006, 01:13 PM

HTT * Divider / 200
06-06-2006, 01:14 PM

oh i see. i usually just multiply the HTT by the fractional divider. less steps.

Thanks! it gets the job done.

Not every board has the fractional divider though.
Mine just gives the speeds. No fraction setting.
setting: 133mhz
stock: 200mhz
FSB setting: 334mhz
(133/200) x 334= Memory at 222mhz DDR444
(250/200) x 200= 250Mhz DDR500
