[koooowweeee]

What motherboard do you have and what memory sticks are you using?

rampage 2 extreme and ive tried 2 different sets of ram. first was 6x2gb corsair xms3 and the other (in now) corsair vengeance, both 1600mhz

Hehe i just joined the club , i used to be a long time lurker on these boards so i thought to finally join to share my celebration.

After having a 920 D0 Dud since the D0 launch, which pretty much could only do something like 3.5GHz on OC.

I thought to do a small upgrade on my system to hold me over till christmas. So i got a Samsung EVO 750 SSD, a 1080GTX (i use a 4k tv as monitor) and the X5675.

Anyway after a bit of overclocking i now have the following system .

Mobo: Gigabyte EX58-UD4 with F11 bios
(C1E, C3/C6/C7, EIST, Turboboost etc all enabled)
Proc: X5675 @ 23-25 multi 166 BCLK
( dynamic voltage set at +1.06 volt (1.296v at burn), and stock QPI/VTT)
Cooler: Scyte mugen 2b + 2x Corsair SP120 (controlled using the voltage control on the motherboard)
Memory: 12 GB Tripple Channel Corsair DDR3 @ 1666Mhz, 8-8-8-24, 1.660V
GPU: 1080GTX
SSD: Samsung EVO 750 512GB
HDD: WD Black 512GB
Case: Coolermaster Cosmos 1000
PSU: 750 Antec Earthwatts
Screen: Samsung 48" JU7500

Currently running intel burn test for 15 runs on High and will keep it running for a little while , but i finally made it past the 4ghz mark. (4.15Ghz with Turboboost on all cores and maxing at 4.4Ghz when some cores enter parked state).

Anyway with regards to temps I'm running idle at around 32°C for the hottest core @ 2ghz, and running intel burn test on the high setting at 71°C for the hottest core.

Anyway so far I might actually not upgrade my platform around christmas and instead decide and wait a bit longer. As this pc now has more life in it than i thought

Don't worry, I have the same motherboard and I run an X5675 in it. Just make sure you update the BIOS to the latest and you'll be good to go.

Well things didn't exactly work out straightforward, but I guess they never do.

To re-cap I bought a X5675. My MoBo is a gigabyte X58A-UD3R rev1.0

I've never tackled a processor switch-out before. My system was a pre-built overclocked one from overclockers.

I bought a cleaning kit plus artic silver 5. The Megahalems cooler looked daunting, but I took my time, got it removed, clean it and the replacement cpu, and got everything assembled. For someone not used to doing it, the amount of pressure that I needed to lock the processor in seemed excessive, so I was a bit nervous when I hit the power.

Bios showed it was running at its default 133mhz x23/25. This is a multiplier-locked processor, so overclocking would have to be using bclk. I reset the cmos, and loaded optimised default. Check that it booted to win10, which it did.

And then my problems started. No matter what I changed, the bios on reboot didn't like it, complained, and reverted to the standard CPU settings of 133 x23/25. Even just setting the 133 to 134 failed.

Played around for ages, no luck. Somewhere along the way my bios got courrupted. Luckly the board has a dual bios, so it was detected and copied across. But the copy was a much older F3 version, instead of F7. And although this version has less parameter changing options, the bios was suddenly happy to allow changes to stick, and I was able to get into windows with over-clocked settings.

On the assumption that I was previously stupid, I decided to download the latest bios, F8L, the one I had originally was F7. But I was back to the same problem of no changes working. Working backwards, the most recent one I could install that would allow changes to stick was F5.

And that's what i'm using. Chip is now doing 180x23, i.e. 4.14Ghz. The only things changed was Vcore to 1.3125V and QPI core similar, and the memory clock ratio down from 10:1 to 8:1 (my memory is 1333Mhz). And disabled turbo boost.

I really haven't stress tested it, except for about 15 mins of IBT @ max, but as it stands this is clocking better than the i930 I took out, plus I've got a couple of extra cores.

So this is the first I've heard of later bios revisions resulting in overclocking not working, but I have seen reports of people being unsuccessful with this MoBo, so I wonder were they using a bios that was too recent.

Anyone with experience have solid thoughts on what max cpu temp is safe, as read by ET6 ? I'm seeing 85c after 15mins of IBT.

 

[koooowweeee]

I wouldn't go about 75-80c but that's just me. I think you should keep it below 90c as a very, very max when stress testing. But in normal use it won't get that high anyway.

Around 35-40% slower in general, more if newer features like AVX/FMA are used.

My 6 x 4.2GHz on 5670 encode video slightly slower than 4 x 4.0GHz on 6700k (no overclocking on that atm, so 4.0 when all cores active).

With h265 the 6700k is even further ahead than h264.

I checked on various sites seems to clock for clock it was more like 15 to 20 % faster (we were looking at upgrading our HP G7's to G9's) - there were comments about some of the newer instructions being very useful for some server type work (like encryption)... I did notice the CPU clock speed was generally SLOWER on the newer xeons (apart from the top end models that hold their value better second hand)

I still have the water blocks for the old R2E board.

It's about 20% but more depending on how heavily newer features are used. My 3dmark physics score was 12.5% better for 6x4.2GHz on X5670 vs 4x4GHz on 6700k

When encoding with x265, the 6700k is very slightly faster.

I thought this series of Xeons were unlocked. Mine certainly is.
I had a quick look on Google and people are overclocking this CPU via the multiplier.

Could be my bios, but it's only allowing either 23 or 25. Unfortunately my experience with later bioses was that it would fall over with even the smallest change.

I don't suppose it's that important. I guess most of the overclocking is done by the bclk anyway. Mine is just set to 22x200 for example.

 

[koooowweeee]

ive been having another mess about clocking my cpu. got it to boot at 4.1(ish) but when i stress test it, it down clocks its self to 3.9 any ideas why? temps are 70c on the hottest core.

Never mind was some turbo setting. Crashes after a few mins of prime95 now back to the drawing board

 

[DragonQ]

What motherboard do you have? Asus motherboards throttle turbo speeds very aggressively so if you want 22x for example, you have to set it explicitly.

yeah its a rampage 2.

ive set it to 22x now. got it at 191 x 22 = 4.2ghz @1.36v

ran prime for about 20 mins and been gaming for a couple of hours so im guessing its stable enough.

just need to work on lowering the vots a little if i can so i can keep the fans on low speed, no idea what im doing tho haha

That's great thanks, I'll have a go later on.

Thinking of going back to water. Only need a water pump. Ive got the rest of the kit baring some tubing.

Might be worth using 3 sticks only while playing with settings, then add the extra sticks back in.

 

[koooowweeee]

Seem to have a options missing. Intel turbo mode tech. Also I can't set my ratio to 21. It's 20 or 22

 

[koooowweeee]

Only got 3 in now. the second set are 3x4gb

Edit. Well it boots at them settings. Only thing I did leave enabled is speed stepping.

Now for some testing

Edit 2. Frozen soon as I loaded prime95

Hey folks. I have a question.

I've had a 5650 in my rig since this thread began, but I'm only now getting around to OC. (And that's only because I now have a Fury X and I suspect the stock CPU was a bottleneck.)

Now, I've got to 20 x 200, but with turbo and hyperthreading off. If I enable these features I need to increase the Vcore, and then temps get a bit high (80s).

My question is - is it actually worth upgrading my cooling so that I can enable these features with acceptable temps? (I'm toying with the idea of getting Kraken X41 - no room around my CPU socket for Noctua or similar.)

Ginga

I forgot what settings I'm running on my x5660 but its running 4.2 at 1.235v (I think) paired with a Corsair H55, temps are good when on full load, I use my system for Video Editing so the cores do hit near enough 100%.
