Xeon Hacking and Overclocking X79/X99 [Beyond X58] - Page 47

post #461 of 1532
Just fired up an e5 2670 yesterday.
Little comparison between 4930k@3.9Ghz and E5 2670@3Ghz.
Ccinebench r15- 1046 and 1030
Firestrike physics - 14.5k and 13.3k
GTA5- well it is strange, For 4930k, sometimes HT kicks in . So in task manager 7-8 threads being used. sometimes not. For e5 2670 no HT used, always 8threads being used.
so , Scene 1- 4930k@3.9 ghz 85fps when HT kicks in. otherwise 75fps. E5 2670@2.6ghz (for some reason turbo does not trigger in gta5) 72fps.
Scene 2- 4930k@3.9ghz 65fps when HT kicks in, otherwise 56fps. E5 2670@2.6Ghz , 49Fps.
How can i lock turbo in e5 2670 in rampage 4 BE , Guys?
Temp- same frio cooler, same crappy chinese paste, same skill of applying it (me tongue.gif )
4930k@3.9ghz prime 95 for 3-5min max 85c.
E5 2670@3Ghz Prime 95 for 10-15min , max 65c

Thanks for the figures. What GPU is that?

I'll see if I can test these 12 core 2011 chips in my R4E soon smile.gif Just give me a day or two.

Gtx670 4gb @1190mhz. Texture, grass, shadow, postfx lowered. But distance scaling, population, vehicle etc maxed.full hd. Gpu was in between 70-90% in those two scene(crowded).
Oh, by the way, locked turbo by disabling speed step technology. @3ghz,e5 2670 >>
Scene 1 77fps around
Scene 2 56fps

I figured this would be a good thread to ask about E5 Xeons instead of making my own thread.

I never realized how cheap these chips are, I was originally looking for a used 5930K because I am going to need the 40 PCIe lanes soon. But after seeing all the cheaper 10+ core Xeons (which all have 40 lanes) and even cheaper engineering samples I am leaning towards a Xeon over a more expensive 5930K (even more expensive 6850K).

I spent all weekend researching about engineering samples and see the early steppings are clocked lower and turbo does not go as high or no turbo at all.
I was originally going for an E5 2683 V3 ES for around 200 but emailed the seller and he responded all cores with turbo is only 2.3 and single core is 2.6. I do game but am not looking for the highest FPS possible. I don't need 120, I would be happy with 60-80. But seeing the low single core speed of 2.6 scared me. Then I saw my contender, a OEM E5 2683 V3 from a server pull that turbos to 3.0.

My question for everybody that bought a E5 26xx V3, were you guys able to lock all cores to the maximum turbo? I saw some X79 boards did but I don't know if X99 can do it as well.

Question 2, do ES samples have any long run issues? They were created for partners to test, so in essence a throw away. Would Intel purposely make them not to last as long as retail.

Reason I ask is the second stepping ES 2683 V4 (Broadwell and 2 more cores) turbos to 3.0 as well and costs the same as the OEM 2683 V3.


So would you guys recommend the ES V4 (16 Core broadwell) or OEM V3 (14 core haswell)? Or ditch the Xeons and save a bit more for a 5930K.

Thanks

You will not be able to lock all cores to maximum Turbo. If you could, they ES vendors would have figured it out a long time ago.


There is no sign of deliberate crippling of ES chips reliability wise. Most of them run just fine for years. Actually some (usually late stepping) ES/QS chips are used in production environments. Back in the 1366 era a good mobo could give you a high OC with a locked E5, and tons of E5s end up being abused that way. The ES among them did hold up.

Many early stepping ES chips have their power saving features disabled and producing more heat for the same work is technically not a good thing in the long run. But it can't be worse than a highly clocked i7.


Which CPU is better for you would depend on your work load. If you do have the right software to utilize more than 6/8 cores then Xeon all the way. Otherwise it depends on the price gap.

@Blameless you describe something here that caught my eye. What's this about "landing on the right strap" and might it be of use to us here? The 2683 mentioned above would be freaking awesome with a Hz boost smile.gif

Thanks for the info.

These e5 2670 run so cool.
sadly, highest stable Bclk i can get is only 106.1-107.1 for now, 3.2ghz all core. Only if someone could find a way to clock them just 4ghz.. i believe they could do that under 1.2v Vcore.

I finally bought a QS E5 2683 V3, same stepping as retail. After 2 days of offer and counter offers I got it pretty cheap and just a few bucks over early steppings ES. I was also pleased that the seller sent me an HWinfo and CPUZ screenshot of the CPU I bought.

Can't wait to get it and play with it.
