thank-you.... 😉

to explain recon-uk
during my overclocking testing Mal has been a great help to me
I am a computer tech by trade but I have alot to learn about overclocking newer hardware
and Mal has been my mentor along the way
just pisses me off that he is right all the time LOL
 
I know truegenius

I just tried this morning to run at 9-9-9-27 Trc 36 which is Kingston and CPUz spec for that ram but no luck
booted into desktop fine but failed two workers in Prime95 blend test
I might have to go back to stock clock and set ram at 9-9-9-27 and then raise clock again but that is a project for another day
getting tired of rebooting and stress testing for now
she is stable and okay for now
Poppa wants to get his game on (metro 2033 or Crysis 2)
not stare at a BIOS screen LOL
 
So you will hit around 55c under P95.

about right
I hit 54c with Intel Burn Test
and 53c with P95
but settled down to about 51-52c

In the far future I might try one of the H-series liquid coolers
but am satisfied for now

only issue is going to move to a place with no AC probably
can easily hit 80f
so will have to use a much lower OC when that happens
hopefully can use a window AC unit in the computer room but not sure yet

you are different 😛 😉



😀 i never asked her (who posted this pic).
To me, it looks like a teddy wearing Eyeglasses (without glasses) and a white doctor's/laboratory coat. 😛
 
This is my legit OC. My 3.48x OC ended up BSOD while running 3D Mark Benchmark. It worked fine after a voltage bump, but then myPrime95 temps hit 57C and I want to stay below 55C.

So 3.4Ghz it is:


Cpu: 1045t
Name: Z1NONLY
Stepping: PH-E0
Frequency: 3401.6
ref*multi: 252*13.5
CPU voltage: 1.344 @ full load
CPU-NB: auto
nb frequency: 2519.8
NB volts: auto
RAM: 16GB 1343 9-9-9-24 1.5v
Motherboard: Gigabyte 990FXA-UD3 rev 1.1
Cooling: Coolermaster Hyper TX3 (w/2 92mm fans) +5 120mm case fans.
OS: 7 64-bit

Can't fit a big HSF in my case so I ended up using negative offsets for the V-core until I was able to keep my temps under 55c peak.

At full load the voltage is 1.344v. I left C1 enabled so the voltage drops when not under load.

I was also able to keep my turbo core enabled. But I had to back the fq down to 3780 with these voltages. (BSOD @ 4000)


* As of 2/26/12, I think I have maxed this thing out with my current cooling.

For the record I am using a negative V-core offset of -0.075 with my MB listing it as 1.35v (I guess it "droops" to 3.44v under full load.)
Max temp at this Fq/voltage/cooler is 55c after two hours of prime95.

I attempted to lower the voltage another notch and make another run at the fq, but it just wasn't stable with the lower voltage. I even tried to "pad" my Novabench numbers by bumping the multiplier on my turbo core one notch....BSOD. I could probably bump the FSB a little more, but I want to keep the HT link close to 2k.

So unless I get some better cooling, (and bump up the voltage) this is all she has ATM.
 
is this enough to get on the list




CPU: AMD Phenom II x 4 925 2.8ghz Deneb non-BE C2
Frequency: 3500mhz
ref*multi: 14 x 250
CPU voltage: 1.53v
CPU-NB: auto
nb frequency: 2500mhz
NB volts: 1.22
HTT frequency- 2500mhz
RAM: DDR3-1667mhz 10-10-10-30 1T 1.65v
Motherboard: Asus M4A77TD 770
Cooling: Hyper N520 70F room idle - 36c max-54c IBT and P95

 
Correct if I'm wrong, but a while ago I saw some testing on the HT link and performance dropped the higher you went. If so I suggest smp to drop that HT as close as possible to stock.
 
Np, I'm sure I did see it before could have been on one of the other tech forums (that overclock one?) Either way wish I could look for it myself but on phone atm. Tomorrow I'll go looking for it.

**EDIT** I went looking anyway 😀 and found this on it, note its not the one i was talking about:

http://forums.amd.com/forum/messageview.cfm?catid=13&threadid=138802

According to this (not the best site to get info from bet meh) increasing the HT to a point does increase performance a lil bit in certain situations. Note this bit here is from 2k9 on AM2+

"The HT Link frequency is not what what we'd call interesting in terms of overclocking for performance. The difference in performance between very low and high frequencies is in most benchmarks non-existing, although we see a noticeable performance increase in the 3D benchmark. Note that the effect of overclocking the HT link frequency depends on what type of video card you're using. IGP's and high-end video cards (for instance dual gpu cards) will benefit more from HT Link overclocking, because they rely on high pci-e transfer rates. Low- and middle-end cards, which are less powerful and have a lower transfer rate, will benefit a lot less. *: Because of the NB frequency of 1.8GHz, we were not able to test HT link performance scaling beyond 1.8GHz. The HT Link has to be equal or lower than the NB frequency at all times due to the design."
 


In a real test, today test, you can find that increasing the HT only can give you problems and not performance. In other way, the CPU/NB is the proper one for get more performance of your rig.
 



so is 2500 HT and 2500 NB frequencies good or bad?
runs real stable but should I try lowering them Saint19?
 


Basically the HT at 2500MHz isn't giving you any performance advantage. I'd go with the 2000MHz stock and try to rise the NB a little more, if your CPU is Thuban core, that NB can hit the 3000MHz stable.
 
Well my initial post stated that it wasn't any good and should be lowered to stock, like I said I couldn't find that test I saw done in 2k10 / 2k11 but I know I did see it and results showed it wasn't good.

I showed that bit as a perhaps I was wrong, looks like I wasn't :).
