Core i5 Overclocking and Feedback

[Cold Storm]

very nice scores man.

great chip you got there.

Yes, I'm having a blast with it. It will eventually end up as my 24/7/Gamer when this case hits the market... http://tv.hexus.net/show/2010/03/CeBIT_2010_It_s_not_size_that_matters_with_the_Silverstone_SG07

Yeah, that case is pretty sweet. Gotta love small factor cases..

I have to say that is a Nice case I always as well have been into a Small form factor here is one of my builds with a mATX Apevia Q-pack2

I ended up with a 4870x2 unfortunetly I never took pics with it when I had it that way But it was really fun!! My specs where after I added the 4870x2 was

Core 2 Duo 7400 @ 3.6
Apevia X -Qpack 2 Modded for 1 extra 120mm fan on top.
4 Gigs G.skill 1066 Mhz
Sapphire 4870 x 2
Asus P5Q-EM
OCZ 700 Watt Modextreme
Western Digital 500Gig 7200RPM 32MB Cache
LG Lite Scribe DVD/CD Burner

So bud I have always been into small form factor when you get that case and make your system fly bud make sure you post pics!!! I think yours would out do mine with that i5 CPU!
What Video card are you going to put in?

I like it! I have never owned a microATX but I had this vision of cleaning up my collection and have one pc do both tasks as a 24/7 and a game rig combined. Plans are to insert the i5 670 and a Sapphire 5870 for some daily 4.5GHz action with air cooling only.

Hard to tell yet, but hoping there is room enough for two hard drives and a optical drive. Supposedly the new case will allow for an aftermarket cooler to fit. It may be a stretch for me, but I plan to build it and use it for at least two years before sticking my fingers in it again lol...

Yeah that case looked like it did have the room for a big after market cooler. That was the one thing I wished my X-Qpack 2 had. I started out with a Thermaltake blue orb and then I had to mod the case when overclocking even higher so I could fit a bigger HSF.
I eventually ended up with a Xigmatek S1283 in there.

What I had to do way cut this little rail above where the CPU sat kind of like this.....

But you would be surprised when you have such little space how creative you get! My best suggestion I have for you when building small **** Especially**** with a new type of case were there won't be any reviews on.

1.Buy the case first.
2.Do the measuring.
3.Then find the dimensions of your parts you want to buy.
4.Then order them.
5. The biggest important thing about building small too!!!! Cable management! Air flow is so limited in there make sure the cable management is good!!!

Trust me from experience

But please post the pics when it's done I can't wait to see them! If you ask me I think it takes allot more talent and planning to be able to build so small! It's like building your own gaming console

Here's a dual core i5, couldn't get wprime at 5ghz, but did a 1m pi

 

[Boneface]

Well installed the new Cooler, Thermaltake SpinQ. My old Coolermaster aquagate must have been going in ther crapper lol cause at 3.2 my temps were 40c and now 30c.

 

[Cold Storm]

Looking good Boneface. Glad to see the temps went down for ya.


4x4... that's wrong.. Just plain wrong!!

Okay Guys I am trying to go up to 4ghz now with my i5 750. Right now I am stable as hell @3.8 with these settings....

Vcore: 1.30
DIMM: 1.65
CPU VTT: 1.21
PCH: 1.10
CPU PLL: 1.875

Trying to get to 4ghz I have tried these as my highest settings so far.....

Vcore: 1.33
DIMM: 1.65
CPU VTT 1.3
PCH: 1.10
CPU PLL: 1.87

Failed after one run each time with LinX. Any suggestions??? An other thought do you think it would be smart of me to leave the PCH and CPU PLL voltages on Auto?

Also the symptoms I am getting with my failures are....Just says LinX stopped.... I am not getting a BSOD's or any crashing?

So would you suggest more Vcore or more VTT's?

Any thoughts and suggestions would be grateful!

***EDIT****

After looking more around this post I am noticing that to achieve at least 4 Ghz an average voltage of about 1.35 or higher is needed. But what are you guys doing with your VTT's? How high are they?

 

[Deleted member 74752]

20mm - I don't have access here at work but when I get home this evening I will send you a link that will answer all your questions for that mb.

Thanks it would be appreciated!!! I almost had it.... 4ghz.! Booted in was running LinX 20 runs made it through 16! I thought I was good and would be moving to Prime95 next. Sure enough on number 16 I failed.

My settings were:

Vcore: 1.356 up to 1.36 in windows
DIMM: 1.65
CPU VTT: 1.21 up to 1.22 depending on load.
PCH: 1.10 In windows when running 1.09
CPU PLL: 1.875

MAX Temps over all with that test:
Core: 67c
Vreg: 61c
Chip set: 28c

Max core temps during that test:
Core 0: 71c
Core 1: 65c
Core 2: 67c
Core 3: 66c

Overall for 4 ghz I would say my temps look okay. I would like to get my VReg down a little bit more but I know they can take up to 100c so I am not to worried.

Any suggestions guys???

 

[johnnyfiive]

I suggest upping the vtt to 1.25v range and the CPU to 1.365v. Run Intel Burn Test and see if its stable.

Here's where I'm at for a max.

4.4GHz

Requires a ton of everything lol.

 

[Cold Storm]

Yeah, my 4.4ghz took a bit to hit.

But, I was able to go to 1.42v for 24/7.

and if you need validation, clicky my siggy


I've found that the PiS need to have the XMP profile on to get the settings right for normal clocks.. Manual setting it, will result in ram errors.. But, if you want to lower clock them.. they love it... Strange.

 

[johnnyfiive]

Very nice cold storm. What do you run 24/7, 4.4GHz? What are the voltages needed for 4.4? (CPU, IMC, PCH, etc.)

 

[20mmrain]

Thanks Johnnyfiive and Cold Storm It great to have some examples!!!

 

[johnnyfiive]

NP man, thats what this thread is all about!

 

[Cold Storm]

Very nice cold storm. What do you run 24/7, 4.4GHz? What are the voltages needed for 4.4? (CPU, IMC, PCH, etc.)

That was when I first went to do 4.6ghz.. With Trident 2000mhz ram. What Sneeky has now.
Since the PiS ran at the higher speeds, I was able to redefine my 4.4ghz to the follow:

EVGA FTW P55
CPU: 1.4375 (Both clocks)
PCH: 1.25
VTT: 1.55
PLL: 1.85

Thanks Johnnyfiive and Cold Storm It great to have some examples!!!

We're all here to do whatever. Like Johnny said. If we didn't want to help, we wouldn't post. Or shouldn't..

 

[johnnyfiive]

That is a ton of VTT, but from what I'm experiencing that is what limits the BIG overclocks. I've never gone passed 1.4v VTT, guess its time to venture.

 

[20mmrain]

Well guys preliminary results..... It looks like I have hit 4ghz stable.... for a long term overclock ever.

My Settings are
CPU Vcore 1.356 (Goes up to 1.36 in windows)
DIMM: 1.64 (Shows 1.65 in windows)
CPU VTT: 1.20 (Shows 1.25 in windows)
PCH: 1.10 (Shows 1.09 in windows)
CPU PLL: 1.875 (Shows 1.875 in windows)

CPU Frequency: 200
CPU Multiplier: x20
PCIe Frequency: 100
VDroop: With out Vdroop
MCH Strap: Auto

Memory Ratio: 2:8
Memory Speed: 1600Mhz
Memory Timings: 9-9-9-24 CMD:1T

Temps
Max core overall 67c
Max Vreg 59c
Max South Bridge 25c

Max Core 0: 72c
Max Core 1: 68c
Max Core 2: 67c
Max Core 3: 68c

Also feel free to comment. Especially on the temps! Also I wanted to ask you guys.... when intel talks about the Max temps. Is that talking about temps overall or temps per core. Like for instance the Max temp on the i5 750 is 72.2. Does that mean for the whole CPU or the individual cores?

Still have to go through the rest of my tests..... but right now I passed 20 runs LinX at 83% RAM!

 

[sneekypeet]

Temps are expected and fine!

I will say this, my 750 has been WAY hotter

Thanks sneeky that was my goal! To hit 4ghz with in Intel's allowed specs. I have so that is great!

Although.... I raised my VTT's a little anyway for stability. It just seemed it was taking Windows 7 longer to finsh booting. After I raised them a tad..... it's gone now.

Now on to more testing!

 

[sneekypeet]

TBH nothing is going to hit your CPU like LinX will unless you run F@H or WCG on it. Its more the worst case scenario for temps, but an absolute for stability

Well I always use two different LinPack programs. One long and one short. So I ran IBT for the short one this time. It passed with flying colors.

The reason I do this is because... I have had LinX Pass and IBT fail or visa versa before. So I always do it just to check!

Now on to Prime 95

But I might run a Vantage Benchmark first! To see how much I have gained.

Gained about 419 points With out going as high as my video card overclock is normally.

You guys quit jacking around and don't let me run away with this...
