If i recall correctly, i'm running 24gb 1333 ecc Samsung memory at 1850 with 3700 uncore at 1.32vtt. Been a while since I've touched the x58 or really any of my rigs. No time to play.

Buffered or unbuffered ecc? I was really tempted to try buying 24gb of buffered ecc but the general consensus from google was that it wouldn't work.

I use 24 GB Micron DDR3-1866 unbuffered ECC, and it works in my Asus P6T Deluxe V2 crossflashed with a P6T WS PRO Bios as ECC RAM. It works also with the original Bios and the crossflash to a P6X58D-E Bios, but without the ECC functionality.

im running 24gb @ 1457mhz with 1.275 vtt (9-9-9-27) -- gotta double check uncore though, think it might be on lowest.

The short answer is that the multiplier for the X5660 processor is locked at 21 but, with TURBO BOOST, the multiplier can increase by either 2 or 3.

The long answer is that turbo boost will change the multiplier for one or more cores in a complicated schedule described by shorthand expression, 2/2/2/2/3/3/. The meaning is described in the following figure where the term "bin" refers to increments of the base-clock frequency. For example, if BCLK=133 MHz, 2 bins = increment of 266 MHz. Or another way of saying this is that the multiplier for some cores can be raised from the nominal value, e.g.,21 to 23,24 or whatever. On the X5660, the multiplier for all six cores could be raised to 23 in some circumstances. In other circumstances, however, turbo boost will only raise the multiplier for 1 or 2 cores to 24 (and keep the other cores running with a multiplier of 21). The main determinants of the exact configuration include the work load and the cpu core temperatures.

all good cheers mate, the guy a few posts up had already answered. As I said, just overlooked something earlier.

unbuffered. Got them for $43 shipped used on Amazon a few months ago. 6x4gb. Really surprised me with the overclock. Can get up to 1863 at 9,10,10,24 1t with 1.68v.

I'm testing the bad set one by one at the moment. If I were to salvage one or two of these sticks and add them to my my good set, will an odd number cause them to all run in single channel and therefore have a negative impact on performance?

You can run 4 and 5 sticks with the nahalem/westmere memory controller, but milage may vary between mainboards.

Ah I forgot to ask, but since you're running with 24GB, what do you have your QPI voltage set to?

Its not genius at all, its a feature of the imc and has limitations,

the main being that only the shared capacity is mapped in triple channel with the upper region of the larger sticks in single channel.

Holy Hell, I think I nearly blew up my shiny new X5670 build.

I was half working up the overclock from a "general" X58 guide, and half reading this thread when I came across the discussion about 1.5X minimum and 2X MAXIMUM uncore frequency. I was assuming 2X and above was A-OK.

I hope no permanent damage was done . . . when getting close to limits, I was staying near 2X when working up.

I'm ending the night with"

4.39GHz
1.4V CPU voltage
1.35V VTT

210 BCLK
21 Multiplier
14X uncore (2944 MHz)
DRAM 1682 MHz (9-9-9-24 1T 1.5V)

Hopefully this is a good start.

Ok, I am still messing with these old X58 systems. I still have my X58A-UD7. Paired it with X5670 or X5675 (can't remember) and it is running at 4.2GHz. This drives a BIOS modded GTX 980 very well. Frame rates are very smooth and consistent. I am thinking this will go to my daughter as she is an avid PC gamer. She converted her husband over from consoles. biggrin.gif

Just bought an entire system off ebay with 920, 8GB RAM, 500GB HDD, and GT9400. This will get a 2TB HDD, GTX 780 and X5660 and will go to a friend of my son's. I have yet to receive it. What can I say? I like playing with hardware (especially old hardware) as much as I like gaming.
