Issues in games after unlocking AMD Phenom X2 555? - Page 4

post #31 of 41
Thread Starter 
Well, I guess I have to thank you for pointing me towards that tool. Before I ran it I doubted it would pick up any errors since Windows 7's tool didn't, but I left it running overnight for 9 hours, and I woke up to see the error counter reading 5120 errors on my RAM. Guess I know where the fault is now..

Two questions:
- Could the faulty RAM be causing the errors I was facing when my processor was a quad-core?

- Wouldn't hurt to take recommendations, so what would you recommend for me to get, Kingston HyperX or A-Data Gaming Series? Both are 2x2GB, 1600.

Have you tried fiddling about with core calibration?
post #33 of 41
anyone else seen the stoch hsf? dude dont unlock until you get a new heatsink. the ones that come with these cpus sre worse that the athlon cpu's. its like half the height. id say its overheating. same thing happened with mine.. plus up the vcore to 1.5 and cpu nb to 1.2 and dont change anything else to begin with. all of this AFTER you get a new heatsink!

as for the fault you had yes definatly at 1.2-4v that was your problem. get some cheap gskill or corsair. both are awesome

Please elaborate, I have no idea what core calibration is..

Well, I had no idea the heatsink wasn't that good. What would you recommend? I don't want something prohibitively expensive, just something decent that works..
I will see if I can get GSkill or Corsair at decent prices here in Egypt, they usually have ****ty pricing here :/

core calibration is the +/- settings per core under the ACC option in the BIOS.
in order to get my X2 555 stable unlocked, i had to adjust core 2 to +8 and core 3 to +12. before these adjustments, anything over 3600MHz would error in prime or BSOD. i now run 4219MHz stable (with the added mosfet heatsinks as suggested earlier in the thread) most people will tell you ACC adjustments do not affect the overclock/unlock of a phenom 2, only phenom 1. this is not the case as some phenom 2's will benefit from the adjustment when unlocked. it's just something you have to experiment with and try different settings. go higher (+2,+4,+6,etc.) to obtain stability at higher overclocks. and 1.2 is def to little volts to power all four cores of an unlocked cpu.

something like my heatsink works well lol. ummm a coolermaster n620 or v6gt would work well just have to make sure they fit the case! mine fits inside my 690II advance with about 2mm away from the sideplate!

Well here's the funny thing, nobody knows exactly what it is but AMD, but I do know that it can be used to somewhat balance cores or add a smaller amount of voltage to just that one core.

I used it on my 720BE and from stock values:

Core:0-+2%
Core:1-+2%
Core:2-+2%
Core:3-+2%

I was unable to overclock the unlocked core, but once I had fiddled with it for a bit and changed the values to a higher value on the dodgy core not only was it stable I was able to overclock it to 3.7 GHz.

The values I ended up using was:

Core:0-+4%
Core:1-+4%
Core:2-+6%
Core:3-+4%

I see, I had no idea, but what would + and - stand for respectively in ACC?

I really couldn't tell you, but if I had to hazard a guess I think that it just add a smaller amount of voltage to that one core to stabilize it.

But don't take my work for gold.

so would I increase all cores values or just try one by one? I still have no idea which cores have problems if any..

Ok, another question:
What would provide better performance? 1 4GB module or 2x2GB module running in Dual-Channel mode?

Thanks.
