not sure how to feel about all the testing that i had done today, 3 pages of A4 to say what can do what and what something cant do, its been a good learning curve i tell you!
settings for all the boards were, cpu vcore @ 1.6v, the vdimm was 2.77v (2.7v on the abit), agp was set to 1.5v and the vdd voltage on the newer epox and abit was set to 1.8v, which was standard. a stick of corsair was used from my dual channel set and then the following tests where done... ( i used pcmark 2002 and 3dmark 2001se for a quick and easy stablity test..)
heres what i found...
my epox 8rda+
worked at 8x133, 8x166, failed at 8x200 (with the corsair memory set to cas 2 2-2-6 at a 2.77V, even on the last test at 2.9vdimm it still didnt want to know)
the highest STABLE fsb i could get from the board is what i have it set to.. 190... and it was able to do this up to a 12 multiplier, used to get to 12.5 but dont want to know now! gutted
my girl friends epox 8rda3+
worked at 8x133, 8x166, 8x200, 8x205, 8x210, 8x215, 8x220 and went all the way to 8x222 with a little voltage kick up to 2.90V... (all at the same settings as my board..)
i would say 220 was the stablist without upping the voltage to much..
my girl friends sons abit nf7-s
worked at 8x133, 8x166, 8x200, 8x205, 8x210, 8x215, 8x220, 8x225 but anything higher even with the voltage up to 2.9V it just didnt want to know.. so again, i would have set it to 220 for stablity...
im happy to say i hit a good fsb on the newer epox and the abit boards, they couldnt clock well PAST using a 10x multiplier with a fsb setting at 200..
for example, my girl friends epox board was able to go to 222, but wouldnt boot into windows without crashing at 11.5 x 200.. it just didnt want to know. same thing was apparent with the abit nf7-s as well..
now what could this be? i have tested the speeds and so on, so what could be the next plan of action? because some of the cpus wont do past what they did do.. for example my 8rda+ would do 12.5x190 but now only does 12x190, why could that be?
i would have liked to hit 2.2ghz on all boards, but they just didnt want to know..
i tried various settings like 215x10.5, 206x11 (which worked with the cpu in the abit board with my FIRST epox 8rda+ board.. not now tho!!), 210x10.5..
now i have thought it would be the cpus 'fault' if you like, but its still very annoying.. voltages used on the above tests, was 1.7vcore and 2.9 vdimm..
but still, very good overclocks all round really.. cant argue with that, esp when they are only £45!! im not going to be using more than a 1.650v on my girl friends and her sons pc, but i will go to about 1.7vcore on my pc, if i can get a bit more speed, but if its only a little, im not going to worry about it and it will be clocked down..
what would be your sugguestions?
if you require anything further, please ask, im sorry if theres to much information there, but its been a long day with these things!!
