PSA: unlocked 8core for x79.. if you cared. - Page 19

post #181 of 198
So it turns out my 4.5GHz and 4.6GHz overclocks weren't completely stable. Even though I could run Aida64 stress test with them just fine I am getting rounding errors in prime 95 no matter what voltage or combination of FSB and multiplier :-(. Looks like its back down to 4.4GHz but man, that sucks.

I only saw 227 gflops @ 4.5 vs 220 @ 4.4ghz according to LinX test with a large memset. I would think numerical errors like that would be more indicative of a memory error. Try backing that down a notch and retest. What settings are you using for Prime95 testing?
I just ran 3 hours of tress testing with y-cruncher, no errors. Room warmed up, lol

After reading through this thread and having a miserable experience with a day one ryzen purchase, my interest in the 1680v2 has been renewed. Currently I'm running a 3930k @4.7 and 32gb of ddr3 1600. I have boot working on a 500gb 960 evo NVME drive on my p9x79ws so I don't really feel the need to move from x79 just yet. Do you guys think if I picked up a 1680 and 32gb of ddr32133 that I would notice some improvement?

You have just about the same hardware as me, P9X79 WS, 960 EVO SSD and prior 3930k @ 4.3Ghz UV. I too questioned whether or not it was "worth" moving to a new platform, but the only thing really gained is higher bandwidth DDR4 mem, As far as raw CPU performance gain, I was seeing ~14k passmark with the OC 3930k and ~20k with the 1680v2@4.5 < look at the cost of processors alone to get you in that ballpark and the premium cost of a 1680v2 upgrade on your existing hardware looks good. To each their own though.

Just went through this thread though the E5-1680 v2 hitting around $750. Definitely spiked my interest, but still it's a bit high. Is eBay the only site to get your hands on these CPU's?

I just moved to X79 the past month from my 4.8GHz 2600k/Z77 mobo. I scored an amazing deal on a X79 Sabertooth mobo new open box with everything for only $150 and I bummed my friend's 3930k for $70. I'm happy at 4.4GHz but its not very good chip I need 1.4v to be stable thought not completely stable as my old cpu.

In the end my results on this chip are mediocre.

I can get it to pass Aida64 stress test easily at 4.5GHz but will fail IBT and Prime95. Heat is not the issue either as according to Real temp I am 15-20 Celsius away from TJMAX.

I am pretty stringent when it comes to OC testing. I know a lot of people online will pass a couple of hours Aida64 and say its stable. And months down the road will say "I've never had any problems on my computer" though they don't remember that one time a game didn't load on the first try, or their internet browser crashed randomly, or that time they booted into windows and their shortcut icons didn't load the little pictures until they refreshed the desktop, never thinking the overclock might be related.

Its sad to say that everyone has a different version of stable, and maybe people who say they have stable systems might actually not. Or say its stable initially and never come back to report on any changes. I think this community is a little better for that at least.

Anyway, for my 1680V2

I was able to Pass

IBT Burn test on MAXIMUM using 60GB RAM for 30 Runs (took around 22HRS)
Prime 95 24HRS
and Aida64 24 Hrs

On my Rampage IV Black Edition
at 4.4GHz (105BCLK X 42 Multp)
with 1.28 Set on the VCore in Bios (netting 1.29 Being bulled under full load with LLC set to auto).

Even though my temps are fine Trying to run IBT or P95 with Vcore set to anything above 1.30 will result in system restart. Seems like it'd be heat related but monitoring everything through Aida64 and Real temp, all my thermals seem fine.

Just playing games, or running Cinebench is fine at that voltage though. Probably because as well all know P95 and IBT TRULY fully stress the system while general usage does not most of the time.

In the end I kind of regret upgrading from my Xeon E5-2687W v2 since I was able to overclock that to 4.1GHz already at 1.24VCore, the extra 300MHz wasnt worth the extra money. To each their own though

I wouldn't do it unless you already had the RAM you are going to use. The idea of buying DDR3 this day and age which is still pretty expensive irks me. I only upgraded because I had the 64GBs of RAM already.

Thanks for the response. And I have 32gb of ddr3 1600 I could use. Was just wanting to squeeze as much performance as possible out of x79. I read your previous post about stability and you definitely stress test for it way more than I do. If I can get an hour of p95 with decent temps in I consider it fine. My 3930k at 4.7 is serving me fairly well. I would want to get at least 4.5 out of a 1680v2 if I got one. But I just bought a Vive over the weekend so I may just hold off on an upgrade altogether.

Thanks again.

I have a hard time justifying $750 on a used chip when a $500 or less Ryzen will be in the same ballpark of performance. And the rumors around the upcoming Intel launches with mainstream six cores and possible lower priced enthusiast lines to better compete with AMD. If the chip was $400, maybe. But not $750 or more.

Agreed $750 is well enough to get me a 1700x with good mobo and ddr4 ram frown.gif
