1366 X58 Xeon 5650

I'm putting this in here as its to do with my X58.

Bought a "viper" pre-overclocked system from overclockers March-2010. GX58A UD3R, 930 clocked to 4Ghz etc.

In the 6 1/2 years I've owned it, I could never get the USB3 ports to give USB 3 speed. In that time I have about 4-6 sustained attempts to get it working. Tried updating the firmware, new drivers, drivers from here and there. Web gave all sorts of advice and I tried the lot. I musta read a thousand pages of forums searching X58 and USB3 Renesas/NEC 720200 etc. Loads of people had problems, all of them got it resolved, but their fixes didn't help me. I'd leave it and come back at it months or years later. I musta spent several 100 hrs on it over the time. In the end I assumed I just had a bad one

Updated to Win10 a few months ago. Last couple of days decided to try again. I'd hoped the new OS might get rid of any incompatbility. But no, my kingston Viper flash drive would just stick at 38MB read speed. Spent another few hrs at it last night, nothing doing.

At work today did yet another search, and I ended up on a page on the US overclockers forum. Saw someone describe a funny that I'd never heard of. If the PCI bus is set to more than 100Mhz, the USB3.0 ports will only give USB2 speeds.

Got home this evening. Could still hear the echo of the front door closing whilst I was hitting the PC power button. Into the bios, PCI is set to 101...hmmm...couldn't be..could it ? Will blow me, 4GB read from the viper now gives me 230MB a sec.

That most be one of the longest unresolved things that finally got resolved that I'd ever had.

I can't definitively say the system arrived from overclockers that way, and anyhow the guy that built the system might've retired by now :).

But the relief of getting something fixed that went on for so so long...well..it's a great start to the weekend.

Had to share.

I remember when overclocking the original chip there was lots of talk that 101 helped stability so you may be right!

I'll try that on mine, cheers :)

Any synthetic benchmarks the usual suspects like 3D mark etc etc. I did this a few years ago found 3 sticks are overall a few % faster score wise which I put down to the system has to make internal allowances for the flex mode.

Give it a try see what results you get!

Same result as I found. As I said before, if you are maxing out memory in use then you are better off having the 4th stick to avoid using swap files, but if you don't really need it then stick to tri-channel only. I have a very nice stick of high speed ram sat in a drawer because 3x4GB is enough for my needs (got a good price on a quad set in mm).

@tangey, thanks for sharing! I'm sure that info will benefit someone else at some point.
 
I ran with 1 stick of 8Gb and it ran the same as dual or triple channel for the applications I used. I stuck with the 1 stick as it allowed me to overclock higher

Tri channel in benchmarks & real world is faster ;) as for the swap file always keep it on an SSD as most of it is 4k read/writes which SSD's excel at ;)

lol that is epic. I was thinking you could have just put in a pci usb3 card. Did you completely reset and go back to default on the bios settings because that also is something I would have tried. Raising pci speed I dont remember helping or altering much


I have x58 and I wondering how X5675 will compare to some more modern xeon cpu which can be 12 or more cores. I see the second hand prices are similar, the cache is more then double and I reckon the newer setup should be better. Lay down some benchmarks for X5675, anything will do winrar multithread etc and it can be compared.

Somebody mentioned will tri channel be noticed everyday, perhaps the best test is browser benchmarks. Again should compare on a few different setups, these are such brief timed tests I reckon its all done in the cpu anyhow

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.

Just to finish off this story. About 3 weeks after I bought my pre-overclocked system, I bought another one for work, it shipped with an ASUS MB, and was a i950@4Ghz. USB 3 never worked for that either. Used the same Renesas chip as the X58.

Just checked today, and yes you guessed it, PCI-e was set to 101Mhz. Setting it to 100Mhz, and it works fine.

So I'm blaming overclockers for this, time for some refunds :)

Heres a thread from waay back on overclockers.net talking about the "advantages" of upping the PCI clock.
http://www.overclock.net/t/656055/x58-pci-e-frequency

and one from here in 2009
https://forums.overclockers.co.uk/showthread.php?t=18049038

And the thread that mentioned USB3 working like USB2 being due to the PCI>100Mhz

Don't know how long I can put of upgrading from xeon 5650 @ 4.4

The itch is real and I keep looking at 5820k
I need something shiny

lol i know that feeling, im still using a I7 950 @ 4ghz and i want to get a I5 6600K or I7 6700K but lack of funds helps with this :D

i keep debating weather i should get a 5650 as i dont really want to spend any funds on my current setup and get a new mobo\cpu\ram

I've only just started using my X5690 in my build and I'm already getting that itch to move to Skylake :D. Only got to 4.2Ghz at the moment (21x200), tried 4.4Ghz (22x200) and 4.62Ghz (22x220 - my P6X58d-e was happily hitting 220 bclk on my i7 950 which easily clocked to 4.5Ghz back then) but these are a bit unstable under extended stress testing. I've increased vcore to 1.4v and vtt to 1.4v w/LLC enabled just to stress test with the intention to dial it down until it's still stable but at those volts it seems unstable. This chip should be binned higher so expected it to clock better (it has a multi of 27!)...Temps are currently at ~67 degrees under stress test.

Any settings anyone recommends to try get it stable at higher clocks?
