x5650 general ballpark of ocing?

daveyb · 24 Dec 2016 at 00:44

hey all,

santas dropping me off a xeon x5650 tomorrow, just wondering whats the general ballpark speeds i should be getting when overclocking it? I currently have an i7 920 D0 stepping stable at 4ghz with 1.36vcore which runs fairly toasty on a h50. hoping to get the xeon past (and hopefully running cooler) that but what should i be aiming for? i've seen people keeping them at 4 and saying its not worth the hassle of pushing it to 4.5, but then other people past 4.5 with ease.

Mine runs at 4.4Ghz with 1.35v (bios) all day long. For me, absolutely not worth the extra volts to run it at 4.5.

Any reason why or just not wanting to use the extra power/temps? On the 920 with my fans at 5v I'm in the mid 50s and at 12v low/mid 40s albeit I had to boost the vcore up to keep it stable with HT enabled at whichpoint the temps went up a fair amount.

If you have the time can you list your BIOS settings for it? just the multiplier/blck and voltages qpi pll etc just so I've got a decent reference point to get started with, cheers mate :cool:

Im going to assume like most people runing Xeons he does not want to add the extra volts as between 4.4-4.5 might need 4x as much voltage increase as 4.3-4.4 there comes a point when you are just going to seriously degrade the life span of the cpu and that is the last thing you want with a xeon

What Harry said.

I'm on my hols are the moment so about 110 miles AFK. I can post my settings when I get back, in the main X5650 thread. Lots of settings/tips in there.

Extra voltage means extra heat and it's not as if you will notice 100mhz difference anyway. For example, my 4670k does 4.4Ghz (core and cache) with 1.275v but going to 4.5Ghz requires a big jump to 1.3v and it's just not worth it. It will go on to do 4.8Ghz but that takes a massive jump in voltage with which I am not comfortable with for any length of time.

Mine runs at 4.4GHz 100% stable at 1.400. I think my motherbord is stoping me going higher.

What motherbord do you have?

4.4Ghz settings

These are my settings with my X5650 if you are interested. this is very stable and i havnt had a single issue since January when I dropped the chip in.

I was running a single 60mm think triple rad and temps under prime95 touched 70C on the hottest core.

this is a P6X58D-E Bios 0803

x5650 should turn up tomorrow (i say should as royal mail/holiday period is flakey), boards a gigabyte gaex58-ud5 rev1. cheers for the settings fella will give em a browse once it arrives.

well i wish you luck,

There are plenty of settings and advice out there on the internet for the X5650, including maximum settings for each of the voltages so you do kill your chip

I would look to get from 4.2+ which will be a good overclock. A rare few will do 4.5Ghz. I had a X5670 at 4.6Ghz but this is clocked higher to start off with.

daveyb · 1 Jan 2017 at 13:35

yeah turned up yesterday, OC settings from the 920 basically carried over @4GHz and did a few runs of IBT burn test no problem. Gonna push it up a bit today I reckon.

Don't use IBT use RealBench instead it is much, much better.

too much vcore needed to get it at 4.4 stable, runs far hotter than expected. Dropped it back to 4.0 for now will try to push it to 4.2 later but I can't for the life of me work out how to get 4.2 and the ram at 1600MHz. The 21x multiplier just resets to 20x regardless of whether turbo is enabled or not.
