Xeon L5639 Overclocking on X58

[jimbob200521]

Original freq. of 2.66Ghz. to 4.4Ghz. with minimal effort.. 6 core X5650 is a nice cheap upgrade. :thumbsup:

Now that I've moved my i7 920 system to server duties, I'm debating nabbing a low power Xeon CPU to swap in. I won't be OCing it so a locked multi is fine. Any decent 4-6 core Xeon's out there that would be low power and run at at least 2.67ghz that are going pretty cheap?

You quoted the answer to your question, lots on eBay, check the seller in the link burpo posted.

Here is an x5670 from the seller Burpo linked for me earlier, I got my processor shipped cross country in 2 days and shipping was free, processor has been great so far.

$79.95 is their price.

Hello. I own a GA-EX58-DS4 motherboard, cpu i7 920 and a friend prompted me to buy a x5650. I have done a quite amount of research and until now i have some questions.
-My motherboard is compatible with x5650 but i have not seen many people using it. Is it suitable for overclock?
-Are there any incompatibilities with RAM sticks? I am not sure which one to buy because i have heard that there are some compatibility problems. I will probably buy 3x4gb 1600mhz with CL9 or lower with 1.6-1.65 volt. Corsair, mushkin, another brand, i am still trying to find the best one.
-Should the temperatures stay below 65 degrees? I have seen many people trying to keep it below 62-63 degrees.

Edit: Burpo, you are a legend

If it was me and I had to pick from what is currently available I'd probably go with this kit, sadly the really low latency DDR3 is long since gone. Off the top of my head I'm pretty sure this is the kit I was running with my X58, and I do believe there was a very limited supply of some 5-6-5-16 Mushkin Redline in the wild long ago.

I'd try to keep the temps under 80, with good cooling you shouldn't ever see it climb that high anyway without a really monster overclock. They are pretty cool running, a simple Corsair H100i can easily handle anything they can dish out and there are probably a few aircoolers around that match that +/- a couple of degrees. The H80i I used briefly even handled it (5670) quite well until it was at very high clocks for prolonged periods of time.

I used this kit, with a GA-X58A-UD7 & Asus Sabertooth.. OC to 1547mhz for me. New 12Gb Kingston kit for $35.

This latency is great but I cant seem to find it.

My motherboard supports triple channel ddr3. There are some g-skill kits in the market but they are not great.
Will there be a problem if I don't buy a ddr3 kit and instead I buy three individually ram sticks which are the same model?
Also, should I keep looking for ram with 1.6voltage so I can get better result?

Corsair h100i is amazing but a little bit expensive. I will probably go to a noctua or another cooler of this spectrum

The X5650 is not multiplier unlocked so you will need to do BCLK overclocking which is similar to FSB overclocking. Some of the W36 series (W3680 and W3690) are unlocked for multiplier overclocking

Most memory kits should be compatible at default speeds and latencies. When you try and run at it rated speeds or higher speeds you may run into issue depending on the motherboard itself. I'd recommend ensuring it's on the latest bios to avoid any kind of memory compatibility issues

These CPU's are rated for higher temperatures than the W36 series even on the TJ Max. If you keep it under 90 degrees and even cooler it should be fine depending on how far you want to push it. As it is a 32nm CPU and there have been power efficiency improvements you wouldn't see it running as hot as the 45nm Xeon's or Bloomfields.

What Ebay stores have people purchased the x5650 from?

 

[Slacker]

Mine was from central valley computer parts

 

[Shmee]

The X5670 seems to be the sweet spot from a quick search, going for around $79 on ebay

 

[Burpo]

Except they don't clock as high as X5650 (on air), before running into temp problems. X5650 is a good cpu for OC, imo..

 

[Shmee]

Really? Isnt it just like a 5650 but with a higher core multiplier? Or is there some other electrical or physical difference that makes them run warmer? I would figure the OC ceiling would be around the same, as you would likely be stability limited by the core frequency at that point? As long as you have a board that can do 200+ BLCK, you are going to be frequency limited, not BCLK or temp limited I would think

 

[Burpo]

Every X5650 I have owned will do 200 bclk, stable & with safe temps. The X5660 & X5670 and X5675 with higher multipliers won't do 200 bclk reliably (stable). The few people that have gotten them that high were using liquid cooling.

 

[jabjab90301]

What air cooler would be recommended for a x5650. ?

 

[Burpo]

If you plan on a high overclock, hard to beat these Noctua's..

Ok I've searched this thread and others and it seems the consensus is that an x5650 would work on a p6t SE.

Just to be sure though, considering many reports were of other p6t models...

Does this work on P6T SE?

Also, I've heard there is some trickiness to getting it to be recognized. Any help?

 

[Burpo]

Yes, and this video shows you settings you can use to overclock..

:thumbsup:

Yes, I have a X5650 on a mild OC just for a HTPC with an old cooler and a couple Noctua fans.

Burpo is more experienced than I at it.

This, they are are going to run into a frequency wall somewhere south of 5GHz (barring someone getting an absolute wonder chip). With enough cooling and enough voltage you could probably push past that barrier slightly. Any 56xx chip is going to run approximately the same temperatures given the same frequency and voltage, give or take slight variances for chip quality. You can somewhat base what chip you need to go for if looking for maximum overclock on what your particular motherboard is capable of doing on BCLK (that is if you know from past experiences with say a 920, 940, etc.)

For example let's assume you are shooting for (not that you will likely attain it, but anyhow) 5GHz and you know your board is capable of doing only 200BCLK before becoming flaky. You would want to go for the 5675 and it's 25X multiplier. If your board can do 210 without issue a 5670 would suit you just fine. 217 and the 5660 becomes viable. This is just assuming you are going for absolute maximum overclock. If you are looking for the least expensive option for a 24/7 reliable daily overclock you can lower your sights quite a bit. I'm going to go out on a limb and say there probably isn't anyone on this forum running higher than a 4.7GHz all core 24/7 overclock, and that's probably being optimistic given that most on various forums settle around the 4.2-4.4 mark. Even a 5650 will get you to 4.7GHz as long as your board is capable of 212 BCLK (assuming again your board is one that supports locking of the turbo multipliers and that you get a chip actually capable of 4.7GHz). The less capable your board is, the higher a multiplier you need. I still don't think I would go lower than the 5660 though in any case, having the higher multipliers available just makes it easier than trying to push crazy high BCLKs IMO.

They can be temperature limited though before they hit the frequency wall, I think Burpo's 5670 (or was it 5675?) may have pushed slightly past my 5670 had it been under water.

 

[ClockHound]

I agree with YBS1. I don't like to admit it, but there it is. Higher Mult FTW!

It's just easier to get a decent OC at low volts and temps with a higher mult. My old 5650 could hit 4.4, but needed 1.4V+ volts and ran in the mid-seventies. Whereas my 5675 runs at 4.5 with 1.33V and maxes at 60c with the same board (Sabertooth) and cooler (D15). (Might be a lottery winner tho)

So... with my tiny data sample, be assured that Burpo will still promote the 5650, because he's just a high voltage, high on BCLK kinda guy.

Just picked up another cheap X58 board for a dev server. Asus P6X58D-E for $90. Will probably pair it with a 5670, so I can have the complete 56xx (95W) set.

What's the run down on MSI x58m and Intel DX58SO?

How well do they overclock? They accept x5650? Reliable?

 

[Burpo]

They'll work, but I'd go with a board that offers SATA3 and USB3, unless that doesn't interest you. I love my Sabertooth.

Doesn't matter to me much. Just wondering because I'm hunting for deals.

 

[Burpo]

This is best deal right now, and if you message the seller, they'll probably do better, because they were at $80. However, you need to flash it first, and that requires an i7 920 or similar just to flash the board for a hexcore Xeon to work with it. Good board for overclocking tho.. Manufacturer refurbs..
