I had to post that for the laugh to be honest just to ease the mind of going insane

So are you saying we can blame you??

Im building a few low cost gaming pc.
Chinese x79 motherboard Q67 chipset (Huananzhi) and Xeon E5-1660 stock speeds. (im not overclocking it but is is unlocked)
and the cheapest s2011 Xeon E5 4620, i have 3 of this. It was only 3 usd each. All of them are damaged (missing caps) but all boots fine. Ideal for light gaming.

This is a frankeinstein machine, 4 way cpu in desktop Q67 s2011 motherboard

When you say damaged caps is that under the cpu?

Yes, damaged caps under the cpu not on the top under the IHS. I bought a few damaged cpu-s before. All of them are works and stable.

These only cost 19 usd incl shipping (1620, 3x4620, 2x2667) the 2667-s are sold and works in dual cpu HP workstation now. ebay
The brown color capacitors is not so important, they only stabilizing voltage spikes and reducing em interferences. They only matters for better overclock and low quality motherboards/PSU-s. Overclocking not az issue here, and i only use good brand PSU.

The later xeons (like v3) has blue colored resistors, that is a critical part.

Im trying to choose between one of these to get E5-2687W v2 / E5-2667 v2 / E5-1680 v2. To put into a hp workstation with a liquid cooler and with some moderate overclocking.
Is there are real performance difference between the 3?

Am leaning towards the E5-2667 v2 as its the cheapest and it has lower tdp then the 2687w v2.

Well 1680 V2 is 8c/16t unlocked CPU so it's GREAT for OC tho' it's still expensive,E5-2687W V2 is also 8c/16t but is locked CPU have really good stock speed 3,4Ghz and turbo 4,0GHz and at the end E5-2667 V2 is also locked have slowest stock speed of 2,8Ghz turbo of 3,6Ghz but is 10c/20t CPU so the choice is yours really depend what mobo you have and what is the purpose of that RIG......GL

Thanks! I did not know 2 of the cpus were locked. Too bad though as the E5-2667 v2 (8c/16t base 3.3 turbo 4.0) is $40 cheaper then the 1680 V2. But looks like im going with the 1680 V2 as its the only one that can be overclocked.

What motherboard you are going to use?Also there is a way to OC locked CPU's on good mobo via bclk but that is a bit tricky I did it with my 2650V2 so now it's working on 3,4Ghz on all cores and boosting 3,86Ghz......

Its going to be a v2 z620 or a v2 z820 motherboard.

 

[bobbybluz]

I see the prices on E5 1680 V2's have gone back up again on Ebay. I paid $150 each for both of mine in the past few months on ones that accepted offers. I like them so much I finally sold my $50 binned 4960X on Ebay for $280 a couple of weeks ago. It's a great thing the average buyer doesn't know about Xeons.

 

[Zyll Goliat]

Well that is a server motherboard I am not sure IF you going to be able at all to OC on that mobo and if you can then how good is their bios for tweaking,you should check on the net before you decide to go into this "adventure".......

After recent discussions and having had a few W3680's come into the shop, I decided to bring them home for testing & use.

In both of my T3500's, 4GHZ was achieved stable(ThrottleStop) but not without temps bumping up to levels I wasn't ok with(mid 70'sC). Still, for short term testing, not bad at all. The interesting part was that many of the GFX benchmarks I ran either didn't go up at all or barely moved, yet CPU tests, like Prime95, were faster by a margin one would expect. This tells me that both of those systems are not CPU bottlenecked to any serious degree, which I was surprised by! I thought there would be some CPU bottlenecking going on, but when you jump from 3.46GHZ all core, to 4GHZ all core and there is barely an uptick in scores it leaves me wondering what the deal is.

Depends on the benchmarks you were using. Most of todays relevent GFX benchs are all GPU bound, so as long as you're using a decent CPU to start with, there will be very little CPU bottlenecking to begin with. Your 3.5 to 4 gig OC will yield very little increase in score, if any, and you pretty much proved that.
Try an old bench like 3D01. Your 500 extra MHz WILL make a difference there.

Its going to be a v2 z620 or a v2 z820 motherboard.

Very unlikely that you will overclock to any worth while degree on either of those OEM server boards.

3DMark, Heaven/Valley/Superposition, FF14 Benchmark, Passmark and few others. As I said, the OC renders the increase in CPU performance expected. What I expecting is for certain games to show and increase as well which was expected to reveal to what extent the CPU was bottlenecking the GPU. What I'm surprised by is the fact that the games I was expecting to be bottlenecked only showed a few percent framerate increase. This suggests strongly that these CPUs are not bottlenecking the GPU as much as I thought...

I am stuck in the "OEM supported features" trap regarding my 1650-V2 which I cannot seem to get passed 4.5 GHz @ 1.3V and approx 60 C using the OEM board (HP-Z620) and looking to do a build around a 1660 V2 or 1680 V2.

I have gotten to 4.5 GHz using XTU only but i cannot set an all-core OC. Once I stress test it, the all core clock drops down to 3.9 GHz which is the advertised max for the 1650V2.

So after being sick of looking at ASUS X79 board all priced over 200 dollars I ALMOST jumped ship and got a 6700k or 7700K but I spied me a Gigabyte board on sale for a hair over $100. Does anyone around here have good experience with these boards? Model: GA-X79-UP4 Rev 1.1, LGA 2011

Conversely if anyone has had success with a HP Z620 Chassis and OEM board regarding OC'ing these WONDERFUL Xeons please share your secrets with me!

EDIT: Purchased a Asus P9x79 Deluxe for 140!!

Yeah, it's a locked CPU on an OEM board. Throttlestop can take it all the way to it's all-core turbo, which is 3.9ghz(makes sense that would be the limit you encountered) and hold it there, but that is the limit. Get an unlocked CPU and you'll get better gains.

EDIT: Purchased a Asus P9x79 Deluxe for 140!!

That's a good board and a fairly decent price!

 

[SlamHammer]

@lexluthermiester is there anyone around these parts that knows the secret to all core OC'ing these x79 Xeons on non-OEM boards?

I've seen stuff ALL OVER the internet of 1650, 1660 and 1680 Xeons (all V2) clocked over 4Ghz on all cores depending on cooling.

I'd love to have a system that benches higher than a gen 7 or 8 i7 for a fraction of the price!

Also about the board, I was surprised they took the offer at $140

It is possible that the 1650v2 is unlocked after watching a pair of vids on youtube from reputable channels.

Additionally, I keep finding posts that indicate that CPU can do a BCLK OC like the following right at the top of the page.

X79 and/or rampage IV OC'ing thread for those of us still left....

Just set BCLK to 125.1MHz. Exactly, I wasn't sure what the setting did till I changed it and then I looked it up to see exactly what the technical explanation of it was. This thing literally can do 2666 mhz memory and 4.5 ghz in it's sleep! Totally different beast at 4.6....fact that it...

www.techpowerup.com

Seems a 125mhz BCLK is possible, but that's with a 1680v2. Your mileage may vary.

I found the datasheet for the xeon x56xx series
Would that be correct as i still confused about the dram voltage as it said in the bios if i go to 1.65v it stated it might damage the cpu or imc but in that picture it stated 1.8v max for ddr3.

 

[Mr.Scott]

I've been running 1.7v for years now.

 

[Edwired]

What that voltage applied to?

 

[freeagent]

If you are concerned just bump your qpi voltage. 1.65-1.725 should be fine

 

[Edwired]

What the downside of doing that? More heat / power consumption / degradation on imc or cpu?
