X58 overclocking club

[MachineLearning]

I'll have some beers.... I'm already on 1.4V... I'll run more benches soon.

TBH I don't give a fk if the CPU dies, these are cheap. And maybe I'll get a better one if I need to buy a new one? What's your (and others') recommended max uncore voltage?

edit: also, I don't use discord anymore (I can tell the reasons via PM if asked), add me on steam and we'll make a group about X58/retro OC? https://steamcommunity.com/id/b-rabbit90/

I've tried to get to the bottom of this many times, there isn't a clear answer but this is my understanding of what's the max 24/7 voltage for 32nm x58:

- 1.45v max vCore
- 1.4v max uncore
- leave PLL @ default, but max 1.88v if you want to raise
- bump ICH up by the lowest increment (50mv for your board?) if you're unstable past 200 BCLK. If you don't make it to 200 BCLK and are unstable, look elsewhere before raising ICH.
- vDIMM max 1.65v

If you want good chips, ignore 2010 and 2011 made 32nm. Buy 2012, date code can be decoded this way. Better silicon quality on average. Personally I have 6 X5675's because of their modest price and good multiplier.

As for the steam group, I think that'd be a valuable addition, however I must ask, what does that accomplish which this thread won't? Genuine question, not being snarky.

Thanks, this should be added to the first post, @tabascosauz or @freeagent, can you edit these to my OP post?

For the steam group, my point is mostly to have some live chat, but it's not neccessary Say to me y'all if I'd put a chat group together!

edit: just wondering, is it dangerous to try like... 1.7V VDIMM?

Not dangerous short term. DDR3 itself is usually durable to high voltages, the CPUs are however unhappy with high vDIMM.

CPU not considered: I wouldn't go above 1.75v VDIMM personally. But 1156 and 1366 both dislike >1.65v vDIMM.

I just remember that Intel warned that their IMC on Nehalem would be hurt over 1.65V but I guess that they just wanted to wash their hands..? I mean I remember triplechannel kits which had 2V or over recommended VDIMM

But good to know. I'll macgyver some cooling for those sticks.

x58 is one step lower than x79 I can admit, it is well indeed. But, it's draw back is, it is based on PCI-ex 2.0 and can not use M.2 drives. (Only Chinese x79 chipset based 1366 socket mainboards's can use M.2 in fact, but only with 2 channel ram.) To catch M.2 performance, the only option is using 8 units of sata SSD's with Raid 0, well for example LSI/Avago 8 channel Raid controller. (A 9311-8i is a good match for example). But, what about CPU power, 1366 socket is too weak without AVX2 and being a 10+ year old micro architecture.

No security based microcode is possible, even for x79 based systems. Currently a CPU without AVX2 is useless, it consumes a lot of power and perform not much. (Sorry....) PCI-ex 3.0 based nVidia 6xx and 7xx are also nearly retired. (Only security is provided lately.) Don't forget Windows 11, it needs minimum 7th. generation high end desktop based on AVX512 processors. Latest security bulletin is here by Intel. https://www.intel.com/content/www/u...-affected-consolidated-product-cpu-model.html

Topaz Video Enhance AI accepts 5th. generation CPU's minimum, Magix Vegas VEGAS.Pro.19.0.0.550_x64 needs minimum 6th. generation CPU's. Those are mostly really essential programs to learn. I have run an Intel Xeon E5-2682 v4 CPU to colorize only one part of Avengers season 4 took a day on Magix Vegas 18 with 16GB ram! There a 26 episodes. So 26 days to run? With Magix Vegas it needs 64GB ram and the time it requires double nearly. Don't ask Topaz Video Enhance. My last run with my GTX 780Ti took 20 days!

Do not fool with x58, really I swear....

And a Model A rat rod makes a crummy daily driver. What's your point?

The thing is that 1156 has (ofc) fewer pins than 1366. So iirc, P55 current handling is ~2/3rds of X58 due to that; This is why voltages are much more conservative for Lynnfield (ex.: 1.2-1.3v imc).

Wrong thread.

It's not about "best", it's about fun for old tech.

Honestly, mind = blown. I've just been thinking that most of those pins are for the third memory channel and QPI.

Well, I guess the old dog can learn new tricks

On the Vdimm, there is no harm in running more than 1.65v. All my machines have been at 1.7v or higher for years.
That 1.65 figure is just Intel's recommended spec.
I have never killed a board or processor using more than 1.65v.

Thanks. They run hot as they're packed so close to each other, I'll macgyver some cooling and put... say, 1.75V?

Just thinking that when I had a Pentium G3258 @ 4.7, I had 2x4 Valueram 1333 @ 1900 @ 1.9V without problems..

 

[Mr.Scott]

There is no DDR3 that runs that hot. None need cooling even in extreme benching situations.

Here's a sauce, and more info

At first glance, one might be inclined to think LGA-1156 based processors are intolerant of high-end overclocking, almost as if by design. This is correct to some extent; a quick glance at Intel’s white papers for socket 1156 CPU’s reveals that there are around 175 pads for VCC compared to over 250 for socket 1366 CPU’s. This means socket 1156 has around 66% of the current capacity of socket 1366, the caveat being that when overclocked, processors from both platforms draw similar levels of current. When overclocked above 4GHz, processors from both platforms will draw around 15-16 amps via the EPS 12V rail to VCC, VTT and some of the other sub –system power rails under full 8 thread load from the Intel burn test (Linx). Assuming 85% PWM efficiency, we’re looking at power draw in the region of 130-140w to VCC on both platforms. The facts point toward tighter current handling tolerances for socket 1156 when compared to socket 1366, especially when it comes to non-connection of VCC/VSS power delivery pins.

There is no DDR3 that runs that hot. None need cooling even in extreme benching situations.

ditto this, D3 runs quite cool. And as for the vDIMM "limit" specified by Intel, I'm sure it's just to cover their asses in some way.

Heeeeyy.... hold on a minute. Now when you mentioned about this, weren't there some articles about the socket burning back in the day with heavy OC?

Yup. That whole article is on that problem in 2009. Not 1366, but 1156. Some Foxconn sockets produced before 2010 were unable to make the CPU fully contact all pins on the mobo. It was probably an issue with their tolerances. Tyco AMP and Lotes were unaffected. To tell, you need to look at the label on the black part - some boards would be tricky, and change the retention to Tyco AMP or Lotes but keep the socket Foxconn... Anyway, that does not affect 1366, and only matters for XOC.

Exactly, Foxconns. I remember reading about those back in the day.

This is why I love TPU and talking about old HW, I instantly remember the news from that era when that product was new..

Yep the good old days : )

Still got it stashed away!

1080 Ti with X58? Damn!

I paired a 2080 with my W3680 based T3500. There was some CPU bottlenecking, but not as much as some would think.

I suppose that at least Intel learned their lesson when they bundled that tiny stock cooler with 4770K.... throttled with it.

On 45nm I think guys were running 1.55v QPI/VTT to hit tha big numbas. I may have ran 1.45v a few times to get my uncore up there, but nothing too serious. My chip was an ES, so it was kinda funny sometimes. Not the haha kind either
