For me better higher VID.
Q9650 VID 1.2125 at 4.5GHz 1.45v - temp more then 80c, i can't cool it now, in summer.
Q9550 VID 1.25 at 4.37GHz 1.5625v - temp about 77-78с

That reads with what I've been seeing in this thread for good overclocks.

I think lower vid chips do run hotter but take less vcore to reach a given speed. Im not sure they will oc higher in general. All depends how much vcore you are willing to use and what type of cooling you have.

Right now I'm on air. I'd love to go water but I think my wife would drown me in it!

I'm willing to put as much vCore as needed as long as I can keep temps in check when stressing for stability.

So, were back to the question of whether volts (and at what value) will destroy CPU!

[OC Nub]

I think its been shown too much vcore will eventually damage/kill the CPU. But we don't know how long that will take. If you intend on keeping it for a good amount of time maybe its best to stick within the Intel specs. If not....enjoy.

[bluestang]

Is 2-3 years a good amount of time? I figure I will upgrade again in 2-3 years.

[OC Nub]

If I was concerned about it and wanted to keep it that long I would stay under 1.3625v, but that's me.

It isn't a BIOS, it's a new version of Easytune.

Micron D9JNM from the first few ram kits i bought them from my local retailer some time ago,
i also have a kit of same ram model number but this kit uses Micron D9KPT, i haven't tried this kit since i bought it so i don't know how this one work in the EP45T board.
and sorry if the picture wasn't clear.

I couldn´t get hold on the D9JNM, the one that I could get was D9KPT, so I bought 2 sets of 2x2.

I tried 4x2Gb 1600 @ CAS 7 @ ~1,80v but they didn´t want to play with that so I settle with CAS 8 @ 1,64v for now, not bad for some value ram though.

It passed 25 loop LinX (2:42hrs) but throw me a error after 4:42hrs with P95 custom blend so i have to tune some more.

sorry i quoted wrong...i meant the F9L bios...

I need to convince work I need a newer PC. If so, I will get the E3110 and the same mobo I got now and see how it clocks. If better than my E8500 then I'll switch them out!

[Ghostleader]

I got up one notch with MCHv but it wasn´t enough she throw me an error after 8hr 56m.

Do you run more than one Prime at a time (I assume you do from the screenshots)? I have been testing my E8400 with just one Prime running, should I be running more?

No your fine. If you have multithreaded prime95 version it will test all your cores at once.

What he did was to run 1 instance of prime95 and then on Task Manager he set affinity for each core.

Some people have more luck in 12hrs Prime that way some don't

[Jor3lBR]

Thanks a lot! I've been running my 9650 at 4500mhz for as long as this board has been out. I never have any blue screens, locks, restarts, absolutley no stability issues at all. Yet i cant complete P95 or Intel Burn test for any length of time. At this point, it doesnt really matter a whole lot because it does what i want it to do. I just want to try other peoples settings to see what happens. If i'm not mistaken, your 24/7 Clock is 4500mhz right? Do you mind posting your settings for that as well? or maybe just let me know what is different from your above post. Thanks again and i will try your settings now.

Hi Nugzo, I finally got around to finalizing that 4500 rock solid stable setup for ya and the others.

Sorry it took me long but I wanted it to turn out perfect.

It's unbelievable but this cpu and board seams to be like wine, the older the better...

5 months ago I needed 1.39vcore for 4500 and never hit 12hrs Prime95 mark. This latest setup was able to achieve that with 1.32vcore, on same cpu and same GSkills PI that where abused a lot with high voltages for World Records achievements. Same thing with the CPU, loads of voltages, high pll (1.85pll) and it needs less volts for same setups everyday.

I'll post soon, keep following the thread.

I think he is running 4 separate primes is because that way it will use more memory. If i run 1 version of prime it uses 1,5Gigs (total) of memory in blend. But if i run 4 instances testing one cpu in each instance. Each prime instance uses 1.5Gigs. Meaning Prime is now using 6Gigs of memory instead of just 1,5Gig.

Ignore what i said, Looks like i was wrong. I was also curios in why he did that. Thanks Jor3lBR for the explanation.

[Jor3lBR]

I finally got around to get this template for you guys, sorry the delay...

This setup came with the summer. I know I was already with 4700Mhz stable setup but this 4500Mhz/4Gb_1200DDR2 is good because of the low voltages and maybe possible on AIR with good Hs's out there. the mem's used where the well known G.Skill's PI edition (4Gb).

Volts used: 1.32vcore / 1.34vtt / 1.50pll / 2.0vdimm / 1.40mch

CPU Cooling: WC Swiftech MCR : Thermalright XWB-1 : MCP655 : NBM-MAT 120mm Fans : 15000 BTU AC in the Room

Bios: F8. (works with any BIOS actually).

This also proves that degradation on these Quads is almost a Myth, this CPU is the same I had from the start and every time I prime95 an old setup I had it just blows the barrier of low voltages all the time. I need less and less voltages to achieve same clocks. This same cpu and gskill had to endure this to be here: http://www.xtremesystems.org/forums/...d.php?t=227129

I always try to send as many pics of the entire testing process (beginning/middle/end) because it shows the real voltage used with all the tests.

Some settings will be hardware specific, like CPU and MCH ref and also memory settings will vary according to what your ram is capable of.

Impressive!
This is all starting to make me want to take mine higher...
What BIOS version are you using or recomend?

[bluestang]

Jor3lBR...that's just awesome stuff!

[Ghostleader]

You do fine with run just one, it´s multithreaded.

I run more then one because I use more memory that way when I run blend and I don´t set the affinity for each core.


@Jor3lBR

Very nice work , some awesome chip you got , keep the good work up.

[Hoss331]

Jor3lBR, was that done on the cryo?

Thank you. Any BIOS will do, I used F8 and F4.

Jor3lBR, was that done on the cryo?

I updated the thread with cooling used. CPU: 1 x MCR220 + 1 x Thermalright XWB1 + MCP655 + 2 x NMB-MAT's

Cryo-Z is only for benching now otherwise the electric bill would be to the roof.

[OC Nub]

Thanks for posting your settings Jor3lBr. I think my q9650 is capable of doing 4.5ghz using those settings + a little bump vcore but temps are out of control. Guess I need water cooling for a stable 4.5ghz. Not sure I want to spend any more money for a 775 rig with the i7 prices dropping though.

[D-an-W]

Watercooling is knocking on my door too OC Nub

Watercooling is knocking on my door too OC Nub

Just not sure what to order or how much of a pita it will be to change out hardware. Is it possible to get a real good setup for $300 or less? I hit 85c+ in LinX at 1.3875v. My CPU needs that or a little more maybe to reach 4.5ghz. Will water cooling get my temps low enough to run LinX?

[bluestang]

I've been looking at the Swiftech H20-220 Apex Ultima watercooling kit that Leeghoofd has in his sig and did a review on.
