hello everyone,

i have a AMD Phenom II X4 955 and with Asus turbo v and thier M4A88TD-V Evo, i got it to 4Ghz. is this a good overclock?

Also with the same software, the ram overclocked to 2.5ghz. (g.skill ripjaw 8gb)

this was all done using the auto tuning option and i have the arctic cooling freezer 13 by the way

Very good overclock on the RAM, didnt even know AM3 borads could support that speed, the 4Ghz on the 955 BE is allso a good overclock but is thos 2 speeds stable?
 
it did actually go up to 4.2 ghz, but the stability test crashed the system, 4ghz is the highest frequency that passed the stabiliity test.
 
iv not herd of a single x4 BE chip being stable over 4Ghz, so 4GHz is probly the best stable clock speed u can get, my 550BE becomes unstable at anything over 3.6Ghz... but its not essacly running on a perfect motherbored, did ya RAM stay stable at 2.5Ghz?
 
well the system did not crash, it passed the stability test, and its alright so far. so meh
 
umm, if thats the ripjaw, i wonder what the ripjawx would do... :O but damn, that nice ram speed if it ture that its stable, what timings?

but yes, befor i get to worked up, can u post screenshots of it saying its speed?

Won't make a difference.
I had 2000MHZ Ripjaws and my 965 C3 could only do 1333MHZ Prime Stable, so I ran them CL5.

On my 1055T 95W cherry picked, I did 1600MHZ CL6.

how comes your 2000mhz did such low freqs?

The IMC can't handle it...
My 1055T could do 2000MHZ benching stable at JEDEC standard.
AMD IMC's just can't take it...

Which is why I ran lower frequencies with impressive timings.
Which is why there's no way in hell OP's is 2.5GHZ.
 
Sorry but im with martini on this one. Thing OP may be looking at his HT speed or Northbridge speed or something. Either that or its unstable. The Deneb/thuban memory controllers only support 1333MHz DDR3 out of the box, and they can only really go up to 1600Mhz RAM through overclocking.

Op, download prime 95, run a blend for a few hours on all threads.
 
sorry for the stir, but i meant 2.2ghz, not 2.5. my bad, please forgive me, simple newbe error.

heres the screen shot:

umm, i had my RAMs on around 1800mhz iirc on my old motherbored... but oh well, yes it does seam AMAZINGLY unlikely to get 2.5Ghz.

edit: 2.2 seams more resonable, but iv only ever seen it done on intel befor...

nice screen saver!
 
It still isnt 2.2ghz, thats your NB speed

Look where it says DRAM frequency, it says 672.0 MHz. Times that by 2 as DDR means double data rate and you get 1344MHz. That 1344MHz is what your RAM is running at :)
 
umm, and nobdy has every passed DRAM 800 on AM3?

Edit : so what "I fancy boys" said was ture about 1600Mhz limit?
