Help with overclocking - Kingston 8 GB valueram system

Last response: in Overclocking

I have tried many days with no luck in getting a stable overclocking:

AMD 1055t CPU
Gigabyte GA-870A-UD3 MB
4 2GB sticks of Kingston DDR3 1333 MHz valueram (KVR1333D3K2/4GR ) - Total 8 GB
SpinQ aftermarket cooler, so temps stay below 60 C

I slowly increase voltages but still unstable after1 hour of Prime95

CPU 3.62 GHZ
FSB 260 MHz
NB 2340 MHz
HT 2080 MHz
Memory 1386 Mhz (260 x 5.33) other multipler is 4 (=260x4 = 1040Mhz), but BIOS will not boot with 1040 MHz. I can only boot with 5.33 ratio. Also inly way I can boot is reduce timing to SPD in BIOS, which is 9,9,9,24,2T.

DRAM 1.7 v (started with 1.5, then 1.56, then 1.6, 1.64 and now 1.7 v)
NB 1.22 v (started with 1.1, then 1.14. 1.2 and now 1.22)
CPU-NB 1.3 v (started at 1.175, 1.22, 1.25, 1.275, and now 1.3v)
CPU vcore 1.4 v (started at 1.3, then 1.325, 1.35, 1.375, and now 1.4)

I can boot in win 7, Prim95 can be stable anywhere from 10 minutes to 1 hr, but the system always gives BSOD.

I am guessing it is the memory problem based on googling, that Kingston Valueram is not a good memory for overclocking.

I will appreciate some help in getting this stable. By the way, I did memtest and the memory sticks are fine after pass 1. Also Linx does not give any error. Even Prime95 has run at times for an hour and a half before BSODs.

Thanks,

- VDIM 1.7 v for DDR3 too high , maximum RAM value 1.602 (+0.045)
- in Oc RAM value need heatsink
- Ram value have limited FSB
- CPU NB too high
- CPU Vcore too high
u must start again from beginning !

Thanks. I have reduced RAM to 1.56 v, NB to 1.16 v. Running prime95 now.

Next step will be to go down in vcore and CPU-NB.

By the way, I was able to reduce RAM multiplier to 4, so memory is now at 1040 Mhz, less than spec 1333 MHz in FSB 260 bus. So I wa sable to get the timings back to BIOS defaults (7,7,7,20,1T). See if runs overnight. CPU is at 56 C, and 10 minutes with no errors.

better than REDUCE RAM MULTIPLIER is DROP RATIO RAM from 1333 (3:10) to 1066 (3:8 ) because your RAM VALUE have limited, type Ram to DC0/both
example :
Set Pc 1600 (1:2) max Ram frequency 850 in CPU-Z
Set Pc 1333 (default 3:10) if OC increase Mutiplier CPU
Set Pc 1066 (3:8) if OC increase FSB in under 300 ( get max performance CAS & Timming ) & perfect for CPU clock
Set Pc 800 (1:1) if OC FSB more than 300

increase FSB CPU = automatic increase Ram freq ,
CPU-Z show 1/2 Ram freq , and ...reality is Ram freq x 2
example : in CPU-z see 700 it's mean 700x2 =1400 higher from standard 1333 ... very good!
remember your RAM have limited OC !

alwasy keep temperature under 60C !

OK, so I set RAM ratio 3:8, reduce RAM volts to 1.56, NB vols to 1.18, and keep everythinh else same; i.e.

CPU 3.62 GHZ
FSB 260 MHz
NB 2340 MHz
HT 2080 MHz

DRAM 1.56 v
NB 1.18 v
CPU-NB 1.3 v
CPU vcore 1.4 v

Prime 95 now runs stable for 4 hours, but then fails for 2 cores, with eroors, and these cores stop on Prime 95. But the rest of the 4 cores continue with no problem. I shut Prime95 after 8 hours. Ststem working OK, but could not shutdown, had to powerdown.

So, what should be my next step? Tem's are OK, below 60C. Reduce CPU-NB CPU vcore ? Or increase?

Please advise, I am quite lost.

Thanks,

reduce CPU NB use minimal in option : 0.025v
in your bios still RAM auto ! try increase RAM minimal option : 0.015

disabled Cool n Quite / C1E
vcore 1.4V for 3.62Ghz very very enough (too high for ..me ) !

Thanks henydiah: So I reduce CPU-NB to 1.225 v slightly above nominal 1.175 v. I set DRAM voltage in Bios to 1.52v, slightly above nominal 1.5v. Leave NB volts at nominal 1.1 v. Cool & Quit and C1E are disabled. Left vcore at default 1.4. Memory is still at 1052 MHz. (It is rated at 1333 MHz). Timings for memory are at Auto in BIOS, I think 6,6,6,15, 1T or something like that.

The Prime95 gave errors within 15 minutes, but no Blue Screen.

Looks like voltage maybe not enough or memory timings too fast.

What do you suggest?

With higher voltage, it at least was stable for 4 hours. For my earlier test with DRAM 1.6v, NB 1.2 v, CPU-NB 1.3v, vcore 1.4V, the prime 95 had 2 core failures after 4 hours, please see results.txt below.

Thanks,

Hi henydiah:

I did exactly as you asked, increased only Vcore voltage to 1.42. I get error only after 45 minutes. Sorry I still don't have software to convert txt into image file. The eroor is

FATAL ERROR: Final result was CCB9467B, expected: 6B5F72DA.
Hardware failure detected, consult stress.txt file.

See whole file below.

I am about to give up. You have any suggestions? I am thinking that 8 GB Kinston DDR3 1333 MHz mempry is preventing the overclock.

Thanks for all your help. - jhaveri

u can look my OC 1055T



in the OC 3.8Ghz X6 coolnquite still active u can see FSB 272 Vcore 1.44
your RAM, Mobo better than my mine , i alway OC start from default Factory Setting - try increase FSB 200 to 240 & test stability anything auto (temporary) for looking MAX RAM FREQ !



in the last night I try OC again & Fix my Cooler & i get 36C when Fullload under stress test

Thanks henydiah: Finally it was through memory multiplier and timing adjustments that I got a stable system at 3.5 GHz. :wahoo: 

Although my memory is Kingston 1333 MHz with 9 9 9 24 timing, I am reducing the mulipler to 4 and running it at 1000 MHz with timing 6 7 7 19. My final stable system is

3500 MHz CPU (FSB 250, x14)
CPU-NB 2500 MHz
HT 2000 MHz
DRAM 1000 MHz
DRAM volts 1.56
NB volts 1.16
CPU-NB Volts 1.25
vCore volts 1.4

Prime95 is stable now for 8 hours.

I could not have done this without your help. Regards, -jhaveri
