Intel Core i5 & i7 Sandy Bridge Overclocking and Feedback

[Chicken Patty]

7 hours stable on Prime95 , just out of curiosity would I even be likely to notice the difference between 1333 and 1600 on my RAM?

I personally haven't noticed any difference when clocking RAM. I think your GPU's will yield much more than clocking your RAM would.

Just passed 8 hours on Prime95 and since I am getting impatient I was wondering if I would be able to overclock my GPU's while still running Prime95? Or should I just wait?

 

[Darkleoco]

9 hours of stability on Prime95 time to move on to GPU's.

9 hours is enough I would say. I don't think I've ever primed that long

I wanted to be sure I would not have any more CPU-related crashes since finishing my Blend I have only had one GPU related crash

What do you have them clocked to as of now? The GPU's...

910/1430 from 810/1250 so not too bad in my opinion might look at getting 920 stable on my GPU's though or just full on 945/1440 like in the Twin Frozr II review on here

Nice. I got my 6850 at 825/1100 from I believe it was 750/1000. I'll go a little higher, but for now it seems pretty stable and it's not a killer overclock. Did notice slight gains in Crysis 2.

On another note, I got a BSOD this morning, so I set my RAM back at 1600 MHz to make sure it was that, so far so good. Just want to verify that's what it was before I tweak it. Don't want to go crazy tweaking my RAM and it's something else.

I need to test if it even make a difference from 1600/1833.. anyone know

 

[Chicken Patty]

As far as games? I've never tested.

 

[N-Gen]

I didn't notice any noticeable increase in gaming, turned them down to 1600 atm for stability. It does show in benchmarking though.

 

[Chicken Patty]

What benchmarks are you talking about exactly?

 

[cadaveca]

SuperPi, memory bandwidth tests, maybe a handful of games, encoding and photoshop can show a difference as well. Basically anything overly memory-intensive.

 

[Chicken Patty]

I know super pi likes memory tweaks, when I was more Ito benching the last improvements always came from that. But I don't really use many memory intensive apps. That's why I ask because lack of experience with memory intensive programs. I don't even use photoshop at all.

Just booted up at this and it's crunching away. Let's see how stable it is. 1.6250v on the RAM. Actually meant to run 9-9-9-28, didn't notice I left it at 9-9-8-28. Oh well, if it's good like this, it's good

 

[BarbaricSoul]

so what is considered a safe temp for crunching 24/7 on a 2600k? I'm hitting mid-60'ties C at 4.2ghz

 

[Chicken Patty]

Stay under 75.

 

[N-Gen]

Mid-60s on air is pretty good.

Ok guys! I just got my 2600K and ive tested stability at stock and never goes over 47deg full load LOL

Im ready for some OCing but I dont know were to start on SB. what are some safe settings?

I used this basic guide:

Just set your ram to its specified timings and try not to underclock it.

And I would start with finding your highest stable OC at stock voltage.

 

[brandonwh64]

I just tried x45 mutli with 1.32V and it wouldnt load windows so I stopped all other voltages were on auto with LLC on highest

You can definitely try to bump up even more than 1.32v because it varies quite a bit between processors, I am on 4.4 and I need around 1.35v for stability, just something I have found myself and heard from other people as well is that the jump from 4.4 to 4.5 seems to include a significant increase in voltage and temperatures than simply doing 4.1-4.2 or 4.2-4.3 I am currently running 1.39v for my 4.4 because I can't be bothered to lower my voltage but you should be able to at least boot at around 1.34v.

Edit: If you don't need/want to go much higher than 4.5 I would just settle for 4.4 but that is just me because I prefer not to take something like a 5-7 degree temperature increase for such a small increase in speed.

Hey man, I think I have some screen shots of the bios settings I used when I had the cpu at 4.7.

But I know its a 53x 2600k, you can see it on my hwbot profile.

Ill look around for those screen shots. (err camera phone shots.)

 

[brandonwh64]

Yea I would love some screen shots! I cant even get it to boot into windows on 4.4ghz at 1.37V It shouldnt take that much for just 4.4Ghz hell some of these chips are 4.4ghz at 1.25V!

I thought the same thing but I ended up sadly disappointed :shadedshu

I had a 2500k before that couldn't hold a 4.5ghz with 1.37 vcore .. I am not the best overclocker but I have managed to get my 2600k way under that amount so yeah there are definitely some bad eggs out there.
