Xeon L5639 Overclocking on X58

[Burpo]

Asus bios doesn't have that option.. I can add up to .6 volts for a total of 1.65 volts (adaptive). After that I have to move a jumper, then voltage can be set between 1.7 & 2.2 volts for extreme overclocking. I haven't moved the jumper.. yet.
I'm not squeamish about about giving these Xeons enough juice to operate properly at the frequency I set. Intel says TJmax is 96C & they will last 10+ yrs. I found out where my cpu throttles and stay below that thresh-hold (with my cooler, about 1.55 volts peak).

 

[Venoom]

well I guess it doesn't matter as the 5650 is fairly cheap.

but I am not sure I understand: are you giving it 1.65V continuously?

if you don't have something like VDroop, how can the voltage drop at idle then?
Is it the C-States that you have enabled?

 

[Burpo]

Yes, i never disable C states & SpeedStep. The chip gets the power when it needs it, but most of the time is idling at around 1.2 volts. Not worried about the CPU, more worried about popping a cap on the board or PS.. SaberTooth was new and has a good power section & the Rosewill 550 watt PS is hanging in there, but I do have a new 630 watt as back up. Spare quad core Xeon also sits next to my rig on the desk.. It's on 24 X 7 & I can't have downtime.

 

[Venoom]

my X5675 is not as cheap as your X5650 but I might give it a try.
Worst case, the multiplier unlocked W Xeons might be cheaper in a year or so if I ever get a problem.
No PSU issues on my side with my overkill 1250W PSU

I will try enabling C states and see if I am still stable.
VDroop didn't work well for me past 4GHz.

Curious if I can reach 5GHz stable enough for a quick benchmark
(probably not...)

 

[Burpo]

Should be easy with your chip. With the 23X of the X5650, I have to up bclk to 218 and volts to 1.6.. but Win7 boots..

 

[Venoom]

do you know how it works when it's an unlocked multiplier?

hypothetically speaking, suppose you have a magical CPU cooler that keeps the CPU lower than 50°C or 60°C no matter what, could you reach 6 or 7GHz by upping the multiplier, and keeping the rest at stock? (for example, 6GHz is 45x133)

Is heat the limiting factor with unlocked multipliers or is there something else?

 

[Burpo]

Yeah, pretty much.. That's why I say "control temps".. You see world records above 6Ghz, but with dry ice or liquid nitrogen cooling. Of course it's not stable.. still, I can do a few things, even at 5Ghz..

 

[Venoom]

I think I am giving up at 4.4GHz...
Tried 4.5GHz yesterday, with a voltage up to 1.45V, and never survived more than few seconds in Windows before a crash or a reboot or a bsod.

I am also having huge issues with the Marvell SATA 3 controller.
I understand it's 5Gb/s and not true SATA3 6Gb/s, but I noticed a huge performance degradation on my SSD : initial CrystalDiskMark benchmark showed something like 400MB/s, now, a week later, I barely get 230MB/s and I have no idea why.

4.4 Ghz is nice. Certainly nothing to complain about. Congratulations!

 

[Venoom]

thanks
but I feel like there could be more to be had, I am very new to overclocking and might revisit it another time

Anyone here have experience with the marvell SATA 3 controller that came out on the high end x58 boards like the ud7?

I know from what I've read its a pile of crap seeing as it was one of the first versions to be made, but I'd like to make the most out of my system and was wondering if theres a way to push it past 410mb read 320mb write, as I can see that the guy above me posted its only 5Gb/s and not 6Gb/s.

 

[Venoom]

ugh, consider yourself lucky you still have 400MB/s, I have no idea how/why performance degraded so much for me.
perhaps it's in my head, but it also feels like the SSD is sluggish, so I am going to move it to a SATA 2 port, and I am considering buying a SATA 3 card, but they're not cheap (around 100$ or more for a nice one that also supports TRIM)

it's a really crappy controller, it's 5Gbps for both ports, and if you don't update the driver, you get tons of BSOD because of it (with a specific error message)

 

[CropDuster]

IIRC the marvell controller doesn't support TRIM. I've always used the SATA2 ports on my x58 board.

But how important is regularly scheduled TRIM to an ssd? I might just switch over since its only like 100mb more read with the same write pretty much.

really?
TRIM showed in CrystalDiskInfo so I assumed it was enabled

 

[CropDuster]

Seems no one is sure and even from I've read it may be dependent on board manufacturers too. I never found a definite answer on it anyway back when I was searching a few years ago.

I remember I found a post on a different forum when I was looking for an elusive fix yesterday...

at some point, the drivers stopped supporting TRIM and were designed for HDD, so if you wanted TRIM, you had to settle for older drivers.

the one I found seemed to support TRIM, and I never had any BSOD because of it (as opposed to the initial driver where I had them very very often)

but I am giving up on the Marvell trashy controller for now, I hooked my DVD writer to it.

Any way you can link me to those drivers? I'm gonna check if I can TRIM when I get home from work.

Still pile of crap. Native sata 2 is better than the marvell sata 3.

Ok so I've figured out the registered ecc issue for x58. I tried a whole bunch of registered ram since they are dirt cheap. Most registered ecc are 1rx4 or 2rx4, those won't work. But 2rx8 ones work with x58, so you guys can probably score some very cheap ram upgrades on ebay, just keep an eye out for the right spec.

 

[Venoom]

can you provide a link to an example?
I'd be interested by 3 or 4 sticks of 8GB RAM on my board (or even 6 ) especially now that I plan on keeping it 2 or 3 more years.

I am posting this on a x58a-ud5 and 2x2G 2rx8 pc3-10600R with an e5520.

 

[Venoom]

I see, that's why you say it's dirt cheap
the 8GB modules are not really cheaper than new ram.

Just wait for the server upgrades. Companies regularly dump tens of blades with 12x8g ram or more. Just have to check for the right ram. There's gonna be a massive flood of server ram when they move to ddr4.
