Remember that it'd be "max performance" for multithreaded stuff only. Definitely doesn't seem worth it without an existing or cheap motherboard.

There is no way im going to get that performance in my price range, it`ll probably end up costing £150 for cpu/mobo/ram after i gumtree my old bits, i think thats good value even if old.

I tried playing pcars on my dual core, slideshow :) More and more games going multi so im thinking its a "cheaper" way into good performance, plus ive just moved to win 10 from 7 and see a big jump in gaming performance although it is only old games im playing.

Thanks for the advice/suggestions, i think my mind is made up, whether it is the right decision or not only time will tell :)

Depends what you're doing. If you're just doing some light gaming, you can bet that even a Haswell Pentium at 4GHz+ will beat a 5650 due to the increase in IPC performance.

If you're also doing multi threaded tasks, then sure a 5650 is probably a fairly justifiable route, as its the cheapest way you're going to get a hyperthreaded 6 core cpu.
 
Possibly, but depends what you're doing. GTA5 runs really well on my machine and seems to use all but two of the 12 threads available. The IPC is slower but if you can get them up at 4.4+ there's little in it and the core advantage comes to the front.

One thing though, mine completely died last night. Rebuilt the whole thing, thought it was completely dead, turns out the CMOS was somehow refusing to reset with the button. Battery out for an hour sorted it. But you have to realise a lot of these boards are old and have had a hard life being thrashed... I personally would struggle to drop 100-150 quid on a 5 year old board.

This is the risk, you never what the board has been put through. If it's been running a 24/7 overclock for 4/5 years, you may only get a few more months out of it before it keels over.
 
I'll do some comparison benchmarking as I've ordered the rest of the bits for a skylake build and I'm keeping the gpu until the next generation are out (780ti).

I'll try gta V, 3dmark extreme and some x264/x265 tests, I want to know how much difference avx will make in x265. No OC on the 6700k as I will be air cooling with NH-U14S, and I will be trying prime95 with the latest avx version.

Reason for the change was £280 6700K and rebooting current PC with X5670. It's either PSU or board, and I don't want to start throwing new bits at such an old system.

Yep, completely stupid for anyone to consider buying a X58 motherboard these days, when brand new Z97/Z170 boards are cheaper, come with full warranty, much more features and no risk.

Sure, if you already have a X58 board with a i7 920 etc, then it's a viable option to get a Xeon, though only if you're doing some productivity workload that actually needs the 6 cores, such as video rendering.

For just gaming, Haswell/Skylake are far superior.
 
Hello, iv been following this page silently for a very long time, but iv come across a problem with my overclock.

My stable settings are as follows

CPU: x5650 @ 3.85Ghz
Motherboard: Asus P6T SE (last BIOS)

multi: 21x
FSB: 175
Vcore: 1.275
CPU PPL voltage: 1.90
QPI/DRAM: 1.275
DRAM voltage . 1.64

as you can see all within very safe limits and has been rock solid.
Until.... i managed to find some of my rare ram on ebay for a good price and went for it to bump my RAM to 12GB,

Now all 6 slots are full i cannot run my ram at stock Mhz, i have to bump it down to 1400mhz which im not happy with. It was running with 6 sticks fine at 1750mhz for a very long time (1750 was the closest i could get to 1600mhz with it been linked to the FSB)

Iv tried bumping up the QPI voltage to 1.3v but makes no difference as well as loosening the timings.

Any tips?
Could i be at my limit with this motherboard before pumping the volts over long term safe levels? (1.3vcore is my limit)

Apparently these Xeons have quite weak memory controllers. That could be the reason why your clocks are lower with 12gb.. Sure one of the guys here will know what to do :)
 
Not sure if that's a Xeon thing, back in the day people were having problems with the memory controllers on their Bloomfield chips when using 6 RAM DIMMs too.
 
looks like to get the 1750mhz i might need to be pumping a lot more than QPI 1.3 into the ram, something like 1.4 it would seem. Going to give it a try and report back.

tried QPI 1.4v with no luck. It seems iv hit a wall, no matter what i try it wont go above 1400mhz

My overclock is only stable when I'm at 1333MHz RAM.

I cant notice any difference in speed, I think you'd only notice in benchmarks.

try up to 1.55 for volts, my ram in my x58 system needs it setting to this before i can get the 1600mhz speed (xmp profile)
 
ok ill give it a crack, what sort of danger am i looking at with them volts tho? this is for a 24/7 clock btw.

im back:
No luck with 1.55v QPI, and to be honest i would not be happy running them that hard for a 24/7 setting.

This, i can't run 6 slots populated as it kills my overclock (blue screens), 5 sticks and perfect for years :)
 
Stop sweating it over voltage. Give t a damn good thrashing!

My memory is rated at 1.5v but I put 1.66v on it.

If you get a good mem controller running RAM at stock you won't need much QPI though. 3 sticks that is. 6 sticks will be harder.

Im completely stupid, but happy so far.
I took the chance it worked out to £135 after selling my other bits, 5650 p6td deluxe and 12gb ram.

Running at 4ghz 1.28v mem at 1.66v 1600 8 8 8 24
Been hammered for two days overclocking testing benching, wash rinse and repeat, its stable and a mega jump in performance over my old cpu/mobo.

Happy as a pig in a poke at the moment.


Ps. If it goes bang in the next three months i`ll come tell you for the I told you so stuff :)
