1366 X58 Xeon 5650

4.84 GHz? That's insane. I can't even get to 4.2 GHz at 1.275 V, although I'm pretty sure that's my motherboard being poo.

I assume it's not safe to go above 1.3 V on a 32 nm chip for a 24/7 overclock?

I'd be tempted to do the same if i knew Skylake was going to bring minimal gains, tough choice.

You going to sell your current stuff together or separate?

I just dunno :p

I'm think I could be 500 quid down after the sale of my x58 system and only notice that I have upgraded when running benchies....:eek:

1.275v is nothing...
Up to 1.35v is recommended by Intel for 24/7 OC. Also Intel states that 1.4v is the MAX VOLTAGE, however is NOT recommended to have 1.4v because you have to consider the Voltage spikes. So don't go above 1.37v for 24/7 overclock.

Alright cheers. I've tried 1.2925 V (choosing 1.3 V or higher makes the warning colour in the BIOS change and I'm scared :p) and it seems stable at 191 MHz BCLK. Still can't get it to stay at 22x though, it's apparently an issue with Asus boards being overly cautious about using Turbo Boost (I never saw this issue with the i7-920 but that would only go to 21x across all cores so maybe that's why). There seem to be custom BIOSs out there that fix the issue but I'm very reluctant to try those.

I'm having flashbacks to my Core i7 where temperature was the limiting factor. That was why I never played with voltages higher than 1.25 V - that isn't a problem now I suppose!

It's tempting. I'm the same as you mate although I would have a Gigabyte board as I like 'em (Gigabyte X99-UD5).

I don't need X99 but at the same time its nice to play with new stuff.

I think it would be out of boredom, rather than need.

WHAT I DO NEED:

New GFX card(s), but currently 970, 980 ain't doing it for me and soon to be outdated.
Really holding out for the new Titan or 390X for a decent upgrade in this area.

hmm. TBH I would look for a used X79 board they're selling for super cheaps. I got my Giga UD3 for £53 from the rain forest brand new unused.

I've seen quite a few Gigas sell on here (the UP4 which is much better than mine) for around £60.

Then chuck in a 3930k and the DDR3 won't leave you with a sore bum :D

22x is for turbo, so depending on the load it can only stay at 22X only when using 6-3 threads, and 23x when you are using 1-2 threads. If you what 4.2GHz all the time just set the BCLK at 210MHz with 20x.

Andy am I right in saying that where there have been loads of supercheap Xeons for the X58 platform there will be the same for the X79 platform in the future. Do the X79 Xeons overclock easy like X58 Xeons or are they locked?

If you are going to upgrade go for it to x99 :D

Tbh it's only the cost of DDR4 putting me off....I can afford it but I'm getting to sensible in my old age....:p

No, that's not right. Turbo is 22x for 3-6 cores, not threads. It should stay there unless something is going above spec (temperature or voltage usually), which the chip is nowhere near doing.

X79 xeons are completely locked sadly. I have an 8 core Ivy that runs at 2ghz and they even locked the strap.

Having said that I paid £100 for it which was robbery and it idles at 23c and maxes out high 30s with all cores loaded. Board was £53 or so so definitely one of the best buys I've ever made.

Benchmark scores were over double that of a 4690k in the OS I run.

Might as well go X99 then as there is no decent Xeon option (sadly)

Just priced this up:

Intel 5820K 3.30GHz (Haswell-E) Socket LGA2011-V3 Processor - Retail (BX80648I75820K) : £311.99
Gigabyte X99-Gaming 7 WIFI Intel X99 (Socket 2011) DDR4 EATX Motherboard : £254.99
16GB (4x4GB) DDR4 PC4-19200C12 2400MHz Quad Channel Kit - Black (HX424C12PB2K4/16) : £209.99
Total : £778.56

That's not too shabby.

I'm getting tempted now. . . I don't need it really but can't deny it would be nice to play with something new.

Sure I could get a few quid for my Xeon X5675, 12GB Dominator GT + X58A-UD3R (rev.2) that would take a decent amount off.

Decisions, decisions
