CPU Overclock List & Discussion Thread

[Jaskanwar Singh]

i use 2GB+4GB stick.
tried removing and changing timings but didnt work.

1st module - G.Skill F3-10600CL9S-2GBNT
2nd module - G.Skill F3-12800CL9S-4GBXL

both of them are rated 1.5v but mobo sets 1.6v. i tried 1.65v too but didnt work.

here you go -

hah looks like you are having the same problem like me.even i failed to tighten the timings of my vangeance 4GB ram by increasing the dram volt to 1.65 but pc boots but there won't be any display.then i have to open my cabby and clear the CMOS then it will work?why is it so guys?btw my mobo has dual BIOS.

@Sukesh1090...

Its really Bad that you can't able to OC Vengeance Ram.. Actually Vengeance are quite Extra-Ordinary to OC... Example....with just 1.62v and loose Timings I can able to Achieve Stable 2133MHZ OC....

@Singh

Try to Increase North Bridge Volt as you know it is related between Memory and Processor.. Also You have two different RAMs and unlikely to support OC . It's really Luck...

Try to Disable Bank Interleaving and see How it goes...(Only If you are using Both 2 and 4GB Rams).

any suggestions with overclocking it.i am using 4GB single stick.btw did you see any performance improvement with increase in ram speed?

 

[topgear]

^^ It depends on the platform and apps you will use

 

[sukesh1090]

^^
I use BIOS bro.jas has already posted its screenshot.mine is also same.

 

[topgear]

^^ I think there's some sort of misunderstanding from my end

I thought you were asking whether performance improves with lower latency or higher memory speed.

BTW, AMD platform such as Phenom II responds better to higher mem speed more so try OCing using the FSB not only raising the multi - Increase in FSb will increase mem speed and latency too but use some benchmark apps and you will see improvement in performance as well

k will try today evening when i get back from college.now i got practical exam in morning thats why i woke up early or else i wake up at 6:30.

I really can't suggest blindly without looking into complete BIOS of the Mobo. I am really concerned about your Hardware, If anything wrongly done with Volts. It might Burn your Hardware especially If we don't know what we are doing.

Regarding Performance , I saw difference compared to stock during Benchmarks and RAM dependent apps. But in overall you won't find much difference except in applications starting and closing. After all, it's 2133 mhz and compared to stock 1600mhz it's quite an BUMP in performance. You won't find much difference between 1333-1866mhz except in RAM applications.

I can suggest you one Thing is you can stop worrying about OC'ing your RAM unlike Processor it's not Much performance gain. IMHO.

ok will try.

^^ really nice and the cooler is also doing a great job but if possible do some extended stability test with prime95/OCCT

BTW, edit the post according to the rules ( you can also see it on the first page of this thread ) to get it listed.

Rules : ( Updated on 17th Jan 2012 )

From now on You have to add a CPU-Z screen shot of CPU, Memory and Mainboard tab along with your forum id / user name and date clearly visible on a notepad / wordpad window and post in the format mentioned below

Here's an example post
*www.thinkdigit.com/forum/1563331-post527.html

GPU-Z screen shot needed if you have OCed your gpu and want to show off though this is optional.

Do post in this Format :

FSB/BCLK :
Multiplier :
Vcore set in bios :
Vcore CPU-Z :

Next target 5GHz. Hope my cooler will be able to keep things under control.

Nice mate.... Very nice

But with SB..... Prime95 is no more used. Majority are using IBT or LinX 64 with AVX for great stability Test

 

[Skud]

Thanks, will recheck with IBT.

Under stress testing (IBT/Linx) temps are going over 80C, although during other benchmarks it remains in 75-77C under load. How far can I push it? Just to see the limit of the chip, not going to run at these settings 24/7.

 

[topgear]

^^ superb oc

 

[sumonpathak]

@Skud...LLC setting plz...

 

[Skud]

Will post detailed BIOS settings once I go home. Probably set it to Extreme.

 

[S_V]

@Skud,,,

Nice mate... But can u please run the LinX 64 with AVX set and let me know the Temps plz.... You are running without AVX ...hence very Low GLOPS...

 

[Skud]

Will do in the evening.

@topgear:

One suggestion, mention the Vcore also in the list in the front page.

Temps are running a bit higher today. This is the slightly updated position:-

*valid.canardpc.com/cache/banner/2252015.png

OCing the RAM was the easiest, just select 1866MHz and set timings to Auto and it boots with 11-11-11-28. Presently running at 10-10-10-24. CL9 fails to boot. BCLK remains at 100.
