Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

Check out the Scythe Mugen 4 cpu cooler.
It is MASSIVELY HUGE.
It is not for systems that have very tall memory heat spreaders.
HardOCP includes it in their AIO cooler reviews because of its high performance and much lower price, cost is $40 - $50.

I wouldn't dismiss your 212 EVO so quickly.
Check out Scythe Mugen 4 Review | techPowerUp and see how your CM 212 EVO compares with the Mugen 4 and Seidon 120XL coolers.

Add a matching 2nd fan to the EVO or the Mugen and you will probably see an additional 2^o - 3^o(C) drop in core temperatures under high heat and load conditions.

Fair, I am using push pull on my evo now, and with PWM controls on just the front fan (the rear is 7volts) I get reasonable max temps of 64-65 degrees in everyday usage/gaming.
With an overclock of 30% and a voltage bump I suppose that isn't really so bad considering my ambient temps get in the mid to high 70's (kill me).

The one thing I really wonder is if and how a good water cooler would out preform in the scenario of higher case/ambient temperatures.
I would imagine that in scaling they keep temperatures lower to ratio of ambient increase, at least higher quality thicker radiators, than a air cooler is capable of.
Especially considering you can space the rad away from other components.

Sure, go ahead. ;)

That's interesting, cause the vcore isn't really that high.

I'am running mine 65nm Q6600 at crazy 1.55v vcore (I don't take no as answer, and that was the only way it would make 3.3Ghz since one core was constantly failing on prime95, it was barely stable on stock clock with 1.325v vid, lol) with a simple CM TX3 air cooler, but the temps still don't exceed 80C. That's why I'am so confident I can push those 45nm chips to 4Ghz-4.5Ghz without destroying them on air. Can't wait for this X5460 to arrive and see how it goes. :)

Yea, that's on extreme side I guess.

Yet still, these 65nm chips are extremely durable, and as for Q6600, only voltages above 1.55v are believed to considerably shorten the lifespan of it. How many stories have you heard about failed 65nm C2Qs due to high voltages? I bet not many, if at all. That's quite a long time I've been running it like that, and still no problems whatsoever. Besides, now that we have these LGA771 adapters, these chips are reaaaally dirt cheap to replace. Even for QX9770 there is a great alternative - X5470. It doesn't come with unlocked multiplier, but x10 is good for up to 5Ghz, and that's obviously more than enough.

I find this interesting, I wonder if I got a well binned chip because my Q6700 (SLACQ) is showing 1.263v and is running at 3.33ghz; I do know that it has a higher multiplier than the Q6600 but would imagine there isn't that much in difference in which they were batched. I say that only because there are QX-6xxx series chips.. but I suppose they would have to be somewhat selective to guarantee a higher multiplier even though it isn't unlocked.

I figured since I am getting a board with an unlocked bios and voltage drop regulation I would go ahead and look into something (x5460) a little more 'powerful' and actually less expensive! than the Q6700 I'm using but I will have to see how high I can get this thing before finalizing what I stick in there.




EDIT!!!:

Today a X5470 was listed for $75 Shipped so I snatched it as fast as my fingers can click, looks like I'll be re-listing the x5460 before it even gets here. lmao
4.0+ here I come!

Please create a detailed hardware list in the System Specs portion of your
forum profile at the bottom of the profile page or in your forum signature.
Be sure to include brand names and model numbers.
When you are done editing or creating your hardware list, save the settings.

If you don't provide a detailed hardware list, your o/c results are meaningless to others.

An X5470 has a 10x cpu multiplier and Max TDP = 120 watts.
The original price was $1467.

A Q9650 has a 9x cpu multiplier, Max TDP = 95 watts and the typical used price is about $150.
A Q9550 has an 8.5x cpu multiplier and typically sells for $90 - $100.

The Q6600 can sometimes o/c to 3.40 - 3.60GHz, and it often depends on how lucky you are with the quality of your particular cpu and your motherboard.

This is a list of AIO water cooling systems at Newegg, sorted by best user ratings:

Prices are subject to change based on sale prices and mail in rebates.
FWIW, I've never had a problem with any of my Cooler Master mail in rebates.

The CM Seidon 120XL's performance is similar to the Corsair H90 and H80i setups.
You need to choose a setup that will fit your computer case and doesn't interfere with your motherboard.
A forum member told me that his Corsair AIO cooler would not fit properly in his HAF XB computer case.

Note: Many AIO models do NOT support mounting the cooler/water pump on LGA775 motherboards.

Spend some time reading AIO reviews so that you can compare cooling performance and noise levels.
I'm very pleased with my Seidon 120XL and it doesn't hurt that the after rebate price was only $40!

Your current push/pull setup with one PWM connection and one fan at 7 volts is not optimal.
You can use PWM with a Y-splitter fan cable to control fan speeds where one yellow fan speed wire is not connected to the other fan and the fan header.

A higher end AIO cooler ($100 or more) should provide superior cooling performance with with extreme overclocks and higher than normal ambient temperatures.
AIO cooler reviews with high Haswell overclocks should provide a good example.
With my mid-range, air cooled dual core processors I've found that each 1^o(C) rise in ambient temperature increases cpu core temperatures by a similar amount.

Most older processors with an EO stepping overclocked somewhat better than the earlier processors with a C0 stepping.
I would hold on to your X5460 until you've confirmed that the X5470 cpu is okie-dokie.

I had tried to do that earlier but I failed to save my info and forgot to type everything back out, sorry about that.

Thank you for the information, especially the following, I somewhat had forgotten about the possibility of non 775 compatibility and that would have been pretty disappointing.

You can use PWM with a Y-splitter fan cable to control fan speeds where one yellow fan speed wire is not connected to the other fan and the fan header.

I am aware, however I will have 7 headers on this new board that is coming, and it has fan control so I will be setting up appropriate profiles assuming all headers are functional.

I used such splitter to set up two SP120 PWM's on my GTX 560ti (Oh my god this is the best thing I have ever done... it is so quiet under load it is brilliant)

Fair point, I thought about it last night and how I should keep it for testing because I can diagnose, not for certain, but with pretty good odds whether my 'sticker' for the mod is the culprit of a non post.

I actually did read this, that's pretty good performance but hard for me to gauge considering I am coming from a Q6700 (65nm) G0 which I'm not sure if may have higher or comparable temps.
However this will come very useful when comparing my x54xx chips and my current cooler.

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

You're welcome.

My favorite review site is HardOCP because they are brutally honest about the hardware that they review.

There's nothing at all wrong with your Seasonic S12 power supply, it's an oldie but goodie.

My Antec TP-750 New power supply was made by Seasonic; it's mostly based on the M12 platform, has an 80PLus Bronze rating and has several modular cables. JonnyGuru, Hardware Secrets and several other top tier review sites gave it excellent ratings. It became my backup power supply when Newegg had an excellent sale price on an X650 Seasonic 80Plus Gold rated power supply several years ago.

I've got a really bad (almost faulty) chip and that's the reason why it overclocks so badly. 1.325vid for a q6600 g0 is really very high. Waiting impatiently for x5460 to see how far I can push it on ~1.45 vcore.

I've actually read that this is a common 'issue' if you will with these Q6600/Q6700 chips, to anyone's knowledge in here is this a common thing with newer Intel CPU's?
I guess the better way to ask this question is, is there considerably less variance in these newer chips I wonder? because as stated I've read fairly often one person having a unfortunately high stock VID.

I'm disappointed that you're willing to cede the high ground to Evan Wins and his soon to arrive X5470 cpu.

The rules sound fair.
Though... there is no toilet paper in my bathroom so I may just self sabotage.

In terms of stability the only concern I will have going into this is temperatures, I am honestly curious myself to see how the x5460 compares to the x5470 considering I have both in hand.
I think for fun I'll see how far I can push this Q6700 as well, it seems a healthy contender in the ring, I would love to see it hit 3.7-8 stable.

It seems like cpu voltage requirements and temperature variations are even more widespread with the original and current versions of Haswell K chips when overclocking. Motherboard models and memory kits can also require higher or lower voltage and bios settings when overclocking. This is why you can't just copy the settings from someone who has the same hardware setup that you have.

It all depends on how "lucky" you are with your hardware purchases.

I will add 3 hardware entries for you, but with your existing Q6700 cpu, you've already won the lowest performer TP prize.

You bring up a good point with the maximum safe cpu core temperature.
I'll add rule that states that the maximum allowed "safe" core temperatures will be 80^o(C), but this might give me an advantage with my non-Xeon processors that have TjMax = 100^o versus 85^o for many Xeon processors.
For this reason, I might need to disqualify myself from the loser award competition.

In Intel 4790K Devil's Canyon S-spec SR219 CPU Overclocking Report, they purchased 3 retail 4790K processors to compare their performance and said:

For this test, we set the vCore at 1.4v, apply 100 percent load, and record the maximum temperature at different frequencies. This test tells us how each CPU handles the same voltage and frequency settings; you can notice that 4790K A constantly maintains the lowest temperatures while performing the best in the other tests.


Interestingly enough, the CPU with the lowest stock VID has the highest temperatures by a substantial margin. Stability is not an issue for this test, and it's performed fast. All of our CPUs were able to maintain full load at 4.8GHz for a short period of time.
