1366 X58 Xeon 5650

Just a quick question please, how much slower would these be 4.4Ghz compared to the new 5930k at same clock of 4.4Ghz?

Trying to decide whether i upgrade or just buy one of these Xeons.

I don't know exactly how much, but it is definitely better than the 5820K(at stock) compared to a x5650(at 4.36Ghz)

x5650(at 4.36Ghz)
-wPrime 1024M - 128.098 sec
-CINEBENCH R15 - 1005

5820K(at stock)
-wPrime 1024M - 189.113sec
-CINEBENCH R15 - 867

Great! Thats good to hear. I was still on version 1 bios until this week lol. On a modded f8b now. Could you post your bios settings for the overclock?

Let me know how you get on with the chip when you get it, I was tempted but then unsure if it would work on rev1 board. I also use a modded f8b bios.

It's in! and it's working! Just running at stock at the moment, but I'm really glad it works :)

Nice one.
I just pulled the trigger on 1. Hoping to maybe get it overclocked to 4.2 or higher. My 920 is rock solid at 4.2(200x21) but its not enough in games like bf4 (64 shanghai)

Enjoy playing with the oc and dont forget to update :)

These CPUS are about 10% slower than SBE clock per clock. I would say overall they'd be the estimated 35% slower than HE. However, you need to ask yourself what it is you are doing with a rig.

For gaming and medium/heavy duties these are fine chips. However, for seriously heavy usage the newer ones are obviously going to be a lot better.

The main issue with these when compared to SBE, IVBE and HE is that, well at least SBE and some IVBE can clock way higher. My 3970x does 4.9ghz under 'noob overclock' IE me not knowing his buttocks from his elbows. That's just me cranking the multi and upping the volts.

Day to day? well as I said I have a 3970x that happily does 4.9ghz but I use a 80w 8 core 16t Xeon because it's far far quieter and happier at desktop duties. I only fire up the big old boy when I want to game hard and run silly MSAA and so on.
 
first overclock, just core voltage increase, nothing else. Tried lowering the voltage but IBT would fail so I guess this is the minimum for 4ghz

Gonna be a big learning curve to get higher I think...
 
Well been on fleabay and scouted out a few options.

Is there much point spending a bit more on 5660/5670 or do they tend to top out at roughly the same level's for the OC?

They have different multipliers which can determine your max overclock.
so it will depend what clock speed you are aiming for and the fsb your board currently can handle may indicate if you would benefit from higher multiplier.

My i7 runs 200x21(4.2GHZ) . im looking for similar/better clock speed so i went for a 5670 hoping for 200x22 or 200x21 or 190x22 etc if i went for 5660 i would have less options to try get that clock speed as it has 21 multiplier. 5650 has x20 i think.
The 5675 was a bit too expensive but has x23

I havnt got the chip yet so hoping it overclocks to the above

The minimum requirement for a X58 board IMO is at least a 200 base clock. You're nowhere near that and, IIRC, my UD3 used to do a 200 base clock to get my I7 950 to 4ghz. Something like that any way, so hopefully she's got a bit more to give.

Either way mate you're laughing there. 4ghz makes this a very fast CPU indeed.
 
Thanks for the reply, has cleared it up.

My current i7 is running 200x21 and I was hoping to at least match current clock speeds.

currenty watching two 5690's depending how much the jump, might take a punt, failing that 5670 looks a good option money/benefit wise.
 
You have a Sabertooth, you're laughing tbh.

I strongly recall that the bclk was absolutely all down to the motherboard, not the CPU. Most pro overclocking guides on X58 all state that you should turn your multi down as low as it will go, then work out what your board can do on the BCLK first. Get it stable, then start adding multi.

It's very similar on high end AMD rigs. You work the bus first as it allows far, far higher clocks with less volts than simply cranking on the multi. I've never seen an 8320 or 8350 reach 5ghz on mutli alone, you'd need about 1.7v.

So always start with the base clock guys. Figure out where you can get to, then add the multi in after.

Sounds good, I'l try that but I'll need to find out what voltages etc to be increasing when testing that (there's load in the bios).

Awesome and thanks for the advice about working the bclk first.

I seemed to remember reading much the same thing when first looking into clocking the 950.
 
I'm going to have to have a punt on one of these 5650's I think, to go into my x58A-UD3R rev 1. Seeing as a few others have one working in that board.
I have my currant i7 920@4GHz with reasonable temps (yes it gets maybe 5° hotter after a longer run)

A bit concerned that if I cannot get any higher than 4GHz that I wont see any difference in the lowly threaded stuff like world of tanks, but I suppose for £65 it doesn't really matter if I have to stuff a shed load of volts through it to get higher.
 
Thanks to this thread for the settings for upping voltages etc on the Asus P6T, thought my PC was stable just upping the BLK to 200 but one of my SSD's packed in due to RAM errors. Got an error on the 3rd round of memtest which then didn't repeat, so I don't know if it was a false positive or if something wasn't happy. 24gb is a lot of ram to test.

After running memtest for 2 days I tried booting into win8 and I was getting BSOD's there too, dropped the BLK to 180 and got errors later on. Upped it back to 200 and put some voltage through it and it is running better than before.

Currently running sketchup renders at 4ghz stable again :)
