Thats tooo BAD News.......
I working now with 3.17 VDDR to make possible Mushkin Level 2 RAMS running on 250 - 260 FSB 1:1 without errors......
I am on STOCK AIRCOOLING by AMD and i want to know if this will be the reason of a future damage on CPU.......
Still waiting the EXOS Socket 754 Clip to install back my watercooling.......
I dont understand why that would hurt the cpu running up the mem volts mr icee.....wierd....I have shoved upto 4v at mine, but 3.64 gives me 270.....beyond that my cpu is maxed.....I have run 9.5 by 280 very stable. I only have a unmodded mach1...I think going colder I could hit 280x10 as my cpu does 270 at pretty low volts. I guess you need to stick to your name and freeze the son of a §§§§§!!!!
Charlie....270x10 I can finish 3dmark completely 90% of the time....272x10 is max possible with alot of luck.....
MrIcee, it all makes sense now cos I just got my mobo from rma and it still wont post..... I guess its the cpu then like you said:( ........ now my problem is how high is too high and at what temp? ....... I have a chiller, not agreat one but nevertheless something that can keep my cpu below 0c, so how will I know now how far I can go without frying another cpu?
Do you guys think this is a Motherboard problem or a CPU problem? If its the mobo i might jsut go for the gigabyte.
Honest guys, I don't know why I lost 2 CPU's at the same volts you are using, buy I did. Both no posts, confirmed by putting the chip also in an ABIT KV8-Max3 and getting FF on my debug card on both boards. Think my next foray when the A64 gets here Friday is a little 5:4 action over 300Mhz FSB....you think that will level the Ti4200 class playing field when the Asus Ti4800SE arrives? ;)

could you rma it? it shouldnt crap out like that...Quote:

Damn....you guys are scaring me know......that sux....
And you leave my 4200 score alone damnit!!!!
No seriously....I hope you have much better luck with the new one..
amd said so in some pdfs that you all are ugly
im really confused with this whole mem controller thing on the cpu...please help me. Basically, if i understand correctly, amd can make the fsb whatever they want since mem controller is on the cpu. therefore they just make the fsb what they want the cpu speed to be right? and just have a multiplier of one? ie 2.2ghz a64=2200*1
Ofcourse I can RMA it but everytime you rma something that expensive you tend to worry a bit....... what pisses me off more is the down time cos Ive only got to play with it a couple of days......:mad:Quote:

yep...i hear ya....waiting sux. i need to put this 9800pro in a damn nf2 system with some pc3000 hyperx. im sure ill do well with a 25xx mhz tbred.
well good luck to ya macro. what proc did you have? just a64 right?
It can be a bit confusing because of the separate LDT bus(Lightning Data Transport) which in essence is the main highway to the Northbridge from the CPU ala the FSB from our XP and Intel systems.
The memory controller onboard runs at its own speed and is the basis for the FSB speed of the system, as we would normally know it from before.
The A64 uses a standard multiplier the same as an Athlon XP, in the case of the 3200 it is 10X.
The memory runs also in this case at 200Mhz, giving you 10x200Mhz= 2 Ghz CPU speed.
The confusing part for many newbs is the relation of the memory speed to the LDT bus between CPU and Nortbridge. When the memory speed is set to 200Mhz, the LDT is 4X memory speed equaling 800Mhz(On VIA K8T800 based boards). Effectively, in our "old" terms giving 800Mhz x2 FSB,1600Mhz, between CPU and Northbridge, as the LDT is also a DDR bus.
NOTE: On nForce 3 boards, the bus runs at 3X memory speed, or effectively 600Mhzx2 DDR or 1200Mhz.This because of a problem on nVidia's part of being able to implement the full 1600Mhz LDT bus speed.
So as you raise the memory bus higher than 200Mhz, so does the LDT bus go in-synch.
This is where things get sticky for overclockers, as the LDT bus doesn't tolerate excellerated bus speeds beyond a certain point, and in the bios it must be reduced based on LDT bus speed settings. On VIA boards its listed as 800-600-400-200.
On nForce3 boards its listed as a multiple such as 3x-2.5x or 2x etc.
So when you hear guys saying they run 270Mhz at 2.5 LDT(On nForce3)....it means the memory is at 270Mhz and the LDT is at 270x2.5 = 675Mhz x2 or 1350Mhz effectively between CPU and Northbridge.
This illustration is of a 1:1 scenario. You can also run the memory at 5:4 ratio's to attain higher FSB like Intel systems. This works very well on nForce3 boards because of the Locked AGP bus...but VIA and their lack of dividers makes high FSB running almost impossible.

I just noticed something interesting.....If I set my mem volts over 3.72 I get hard drive corruption, and my video starts acting up.....It doesnt matter if I am overclocked of not, right at exactly 3.72 and up this happens.....so there is obviously some connection with the mem volts....
tried 3.85v yesterday but it didnt help to get 275 1:1 stable
think my cpu was maxed out but its running pretty hot after a while too using a lousy prometeia mach 1 without r404
it just cant hold the temps down and so the cpu needs much more juice and it wont even last 1 full run till it crahes cause it runs hot
think with some better cooling i might be able to do 275 1:1 or even more ;)
i get hd corruption at 320fsb though , else i would have done 337 fsb 270 ram on my run yesterday
btw what tool do i need to do 560+ core on gpu ?
Looks like we are in the same boat Horus....I ran 337/270 x 8 without a prob (ldt at 2x instead of 2.5 though) and tried many benchmarks.....seems to be identical to running 270x10 1:1
hmm it really wasnt any faster ?
i did some tests yesterday 200/200 and 308/200 at same ldt multiplier
results are carhigh/lobby low/lobby high
200/200 98,6/281,4/129,3
250/200 100,8/285,4/131,1
308/200 99,9/284,6/130,3
at 308 it went down again , i lowered ldt multiplier from 2,5 to 2 i think but not sure if it wasnt 2 already at 200/250
