Hi guys, I'd like to share my OC stats and I'd like some advice.

My rig is in my siggy so as my RAM OC.
Vdimm is 2.1V.

I'd like to get up till 1066MHz, but
1) i'm not certain which timing should i heighten OR should I increase the Vdimm?
2) Did anyone tried this on an E8400 at 3.6GHz? How's the FSB:DRAM ratio?

Or is the above impossible and I risk spoiling smtg?

Here's a caption of my current OC


I don't know why my ram is written as DDR3 in CPUZ.

Added on November 2, 2008, 3:01 pmBTW i notice with the current settings of 4:5 at 1000MHz, I notice FIFA08 runs faster than my previous settings of 1:1 at 800MHz. Can anyone explain why?

Try Everest bandwidth benchmark to see the difference between both setup.
however, pushing the ram alone itself, won't yield much increase in performance.
if temp./ocability allows, try 8x500 1:1 should be a sweet spot.

& i'm curious wondering how u got ur 3gb ram runs at dual channel symmetric mode?

I'm still new to OC-ing btw. Based on a review, my mobo can only OC its FSB up to 420MHz which I've no idea what to put for my proc voltage. I'm limited by my mobo which is too bad.

Could you explain to me why my current ratio of 4:5 feels faster than my 1:1 setup? Any valid reason?

About my rams.. I don't quite understand your curiousity.

The possibility is that the bandwidth of 1000mhz C5 (4:5) is higher than 800mhz C4 (1:1)
that's why will be good if test it with everest bandwidth benchmark to confirm it.
@ the very same fsb for both setup, it's either the extra mhz made the difference or performance level (trd) does it.
i'd say if it's the mhz itself, then the difference is minimal due to looser timing as well.

as for my curiosity, nvm bout it
it might be cpu-z don't know display async. mode.

I've reverted back to 800MHz with 4-4-4-12 latency.. Suddenly I feel everything is ok.

BTW, when I ran IBT, i got failed results. Any particular reason why i got that?

u mean ur 800-c4 passed ibt but not the 1000-c5?

might be not enough vdimm for that,
or, try 5-5-5-15

Umm even at 800-c4 it failed. My vdimm is 2.1V which is what recommended by corsair (on the packing of the RAMs that is).

im using....

AMD X2 3600+
Corsair XMS Twin2X1024-6400C4
Gigabyte GA-M51GM-S2G Mobo
Coolermaster 520W PSU

is there any posible to overclock?
im new for overclocking....

You can try to input 2.1V for Vdimm, 1000MHz, and 5-5-5-12 timing. Worked for mine

[ i have been overclocking CPU's + GPU's for a while now and stumbled across this site quite a while ago, as this is my first time posting here, i would like 2 know what u guys think of my Corsair XMS2 6400 CL4 and AMD 4000+ Overclock. please if u have any advice or questions donty hesitate and ask me as i would love to push this clock even further.

ok here i just wanna to ask you something about loosing the ram timing..erm i got a bit limitation during my ocing project which is my VDIMM voltage.The highest i can set is 1.95V . in amd system, by lowering the multiplier it will automatically oced your ram..now i am using the multiplier 12.5x141=3.012GHz at 860MHz.planning to reduce the multiplier to 12x 151=3.012GHz @1000MHz ..but after i set it into 12x 151=3.012GHz, my system won't boot.. due to the limitation by the ram.when i refer to this thread.suppose the corsair DHX C5 have capability to achieve >1000MHz easily with 2.1volt VDimm..Since i cant increase my vdim, the only option i prefer rite now is loosing my timing.Hope sifu or gurus out there can tech me the correct way to lost my timing by using memset..here my rig details

AMD 5000X2+G2 @ 3.012GHz
Asus M2N-E(limittation in Vdim )
Corsair DHX C5 6400@ 860MHz @1.95V|
5-5-5-15-23-2T(my question how to loose this ram timing ???..can give me example on loosing the timing)

here also i attached my ocing details:

what did i get when i oc my RAM??
i edi oc my proc,mine was amd x2 5600+,stock freq was 2.9ghz currently running at 3.15ghz...
thank in advance...

this thread died so long time d.

how high should my vdimm be if i oc my Corsair TWIN2X4096-8500C5DF to 1266mhz +?

Hey, is it true when using 8g of ram for our pc doesnt give any extra performance or indirectly is a waste.

I'd like to know that too, awaiting reply.

someone please start V2... i sold my corsair already @_@
