1366 X58 Xeon 5650

I wouldn't expect the higher SKUs to clock higher necessarily, it just might be easier due to the higher multipliers. Not having 23x available it kind of annoying since it means I can only get above 4.2 GHz on a single core, but it's not really worth getting yet another chip just for that, especially when it's such old technology.

Not the fastest but still works fine in 2017, not something that could have been said about 2001-era chips in 2009.

They're all exactly the same CPU, just binned higher. It's still a lottery, you might get an X5680 or X5690 that doesn't clock any better. If you can get a good deal on it then it's worth the risk I suppose.

Most will hit 4.2-4.4 provided you have the skill and patience and cooling

http://androidcreations.weebly.com/cpu-binning-explained.html "These high binned high rated CPUs tend to be great overclockers". I think it makes sense.

At the price of £30 or £40, I don't think it's much of a risk. Hopefully, the one I get isn't useless.

Ok, old school overclocking is not as straight forward as today, and I would appreciate any help. Can the ram be clocked independently? Mine is 2000MHz, but shows up at 800MHz (so I assume 1600MHz). Can I adjust this on it's own. Sorry for my ineptitude.

RAM has multipliers. If it's at 1600 MHz I'm guessing you might using 200 MHz BCLK (with an 8x RAM multiplier)? If so, change it to 10x.

Thanks. I will have a go.

I actually have an X5690, see my project log. It tops out at 4.4GHZ at 1.4v with custom watercooling and cost considerably more than £30 or £40, in fact cheapest I've seen is £100 for an X5690 and that's still cheaper than I bought it for. If you think paying double for an extra 100-200mhz is worth it, that's up to you but in the real world you won't notice the difference.

It's definitely not worth the higher multi in retrospect. After spending a long time playing with multi's and bclk on my X5690, the best I could get was at 22 x 200. I also got it to post at 22 x 206 but not completely stable. 22 seems to be the sweet spot and even numbered bclk. These Xeons don't seem to like odd numbers for multiplier or bclk. In retrospect I'd have just bought an X5650 and then I'd not hesitate about getting rid of it all for a new Coffee Lake bundle as I paid a bit for it when I got it. Those extra cores really come in handy, which is why I'm trying to wait til Ice Lake for the 8 core chip before I upgrade! The Xeon's are still very much worth it, provided you don't get carried away in finding one!

Interesting. My X5650 @ 4.4Ghz only needs 1.35V (in bios) which translates to 1.344v under load in Windows.

Proves the point about not needing more than an X5650 it seems.

Maybe your motherboard has better caps than mine as well, I bought mine when the i7 950 came out and it's been through hell over the years. If I had another motherboard, a R3E or Sabertooth or something, maybe I'd get more

I have LLC turned off as well, so voltages don't go up under load. And C states and all that power saving stuff are off too. I'm still happy with the speed.

I haven't paid anything as yet but it does seem like an unwise decision to pay more for something that is essentially the same.

I need some advice here though:
Would it be wise to get the X5675 (£38) which has a 12% better single thread performance than a X5650 (£26)?

I want to be certain that I'm buying the optimum performing CPU for gaming. Videos on YouTube suggest that even the X5670 does not bottleneck a GTX 1070 which means I'd be set for a few years as I'm only looking to get a 6gb 1060 for FHD.

Only if you're not overclocking.

If planning to overclock then my advice is to get an X5650/60.

If not overclocking then yes, get the fastest Xeon compatible with your motherboard that you can afford.

Is anyone using an Asus P6X58D-E board with these X series Xeon's? Are they any good for general use as well as overclocking?

Yeah they're good, that's what I'm using. I've got the EKWB Copper waterblocks for the chipsets and VRM's too. Not sure how it compares to a Sabertooth or Rampage III Extreme though. I was thinking of getting one of those, might get my x5690 more performance. Also USB 2.0 & 3.0 ports get a little unstable also gets very unstable even if the rest of the machine is stable, my leds on my keyboard and mouse flicker, etc. Not sure if it's my particular motherboard.

They're a bit fiddly for running tubing but hard tubing might be ok. I'm going to revert to passive for the mobo I think because tubing it is a pain and I'm not sure if there's even any gain, although I remember before I put the blocks on them they did get toasty on air...

That's great! Good to know it will work! What's the max I should look to pay for one of these boards, as this would only be a cheap build to tie me over for the next 6 months.

Would you say that the VRM's have to be cooled, or could I just run a decent be quiet! air cooler and clock to 4ghz?

4ghz is easy on this board, it'll do 4ghz without breaking a sweat. I'd suggest having decent case airflow and also a be quiet or noctua heatsink will do the job.

Price wise there's quite a few of these knocking about auctions, expect them go to for around £100, in which case it might be better to look for a Sabertooth or Rampage for that price!

I got 3.8ghz on a 5670, undervolted too.

KungFuSpaghetti · 7 Nov 2017 at 13:15

okay good to know, will keep my eye out on ebay for a board, there's a couple with bidders, no idea what these tend to sell for though.

You can check sold listings to see the price they've been going for. There's two versions of this btw. There's P6X58D-E and Premium

You should be able to get more out of that. 4ghz below 1.35v should be possible. Try 22x180, 22x184, etc. Even numbers work better than odd numbers. 22 seems to be the sweet spot for multiplier, even if your chip can do more
