1366 X58 Xeon 5650

Recently got my X5650 stable at 4GHZ.

I had been using OCCT and decided to download IBT.

Talking of Gflops I'm only getting 36 on my X5650 (P6t Deluxe v1 Board). Running standard IBT which seems to choose 1024 Memory.

The result column shows the same number each time so I'm pretty sure it's stable. Not one BSOD but I gather that this is pretty low.

Current settings:

Freq: 200 * 20
Uclk (uncore) 3024
QPI/VTT : 1.2025
CPU VTT : 1.296 (auto)

Running 12GB ram - 2x4GB + 2x2GB triple channel.

I pretty much followed this guide in getting my current settings:

So far I'm seeing posts which suggest QPI/VTT voltage levels and Uncore frequency as being relevant to the results. Currently as you can see my UCLK is about 1.8 x memory frequency. Should I lower this to closer to 1.5?

Any help / advice would be welcome or am I worrying over nothing?

Edit : curiously Just ran a quick standard 2 cycle test and got 50 & 53 Gflops so it's not that consistent.
 
Just Got my x5670 @ 4.2 stable.
Ran 5 round but i also ran 10 rounds too but forgot to take a snapshot. Spent 6hrs running tests so was getting nice and toasty under the D14.
Going to try lowering the QPI/VTT

It look normal?

Just finished installing my X5650 like an hour ago and bumped her up to 4GHZ no problems:) so far so good off to do some testing.

Been playing some games the last 2 hours and not one problem :D

Hmmm from this looks like I might be able to squeeze some extra life out of my P6T/i7 920 combo.

Has anyone with the P6T (non-deluxe) had issues with memory slots failing? I've got one which is a bit temperamental and only registers on occasion. Not a problem with the DIMM as it works in another slot but then I lose triple channel when moving it.

Impressed that the board/CPU has lasted over 7 years!

Might I guess it's one of the channel B slots?

I'm not actually sure, not really had chance to look further into it. It's odd thought as CPU-Z shows the slot as populated but the memory's not there in Windows or the bios on boot. It's whats making me decide between getting one of those Xeons or go for new build. Does seem to be intermittent to top things off

Exactly the same as this

Well my saga goes like this:

When I first aquired my board all 6 slots were functioning (as I remembered .. but .. ). I had a thermaltake venomous x which requires tightening a bolt in the center to add pressure. This killed the B slots completely. That board went back to Asus. 1 month later a new board arrived and after testing the slots with stock cooler I fitted the Thermaltake making sure I didn't apply too much pressure.
Slots B went dead again. Unbelievable.!

At that point I had 4 sticks and I populated channel A and C with them and forgot about tri-channel. I also got rid of the Thermaltake as a dangerous proposition and bought a Corsair H80 which has been on ever since.

So coming to the very recent past ie. fitting my X5650 a week ago I decided to try re-ordering the memory. I also checked the pins before fitting the CPU because as tribz mentioned my fear was the pins got bent with the pressure of the Thermaltake but they were 100% perfect.

Following the Asus recommended chart I populated A1A2 C2 B2 and all memory registered. Cpu-z reports tri-channel.

I also understand that the black slots will only work under certain conditions so perhaps back in 2009 I had not understood correctly. I still have not tried the black slot as I think you need to have 6 sticks before you do.

Currently I have 2x4GB and 2x2GB memory only one black slot is in use A1, so by the rules I get 6GB in tri-channel and 6GB in single channel mode.

I'm sure you've probably tried all configurations but if not try just the orange slots only first and see how it goes.
In my case it would have been a hell of coincidence if it were due to bent pins as I couldn't see how two motherboards could end up with a Channel B problem.

The Asus boards are great when they work but they really do seem finicky and behave strangely sometimes. I think they are female. ... sorry ladies only joking. :-0)
 
Can anyone recommend a decent mid-range air cooler for my X5650 on Gigabyte ex58-ud5? I'm running 6 sticks of tall RAM so this limits me a lot with larger coolers. I'm ideally looking to spend no more than £40ish.

Thanks :)

Hi

When i installed my x5650 last week i also got a new cooler to go with it and its this one.

https://www.overclockers.co.uk/antec-h600-kuhler-120mm-aio-liquid-cooler-hs-013-an.html

It really is quite impressive for the price:)

I did look at the new kuhler, but I'd really rather stick with air rather than AIO. The Thermalright True Spirit 140 Power looks perfect (good reviews, no probs with memory clearance, in budget) however it appears to be out of stock everywhere in the UK - apart from one or two places with inflated prices :(

Any other suggestions? :)
