higher cpu multiplier worth it

[OhYou_]

is it worth upgrading to the next highest cpu model if the only difference is +1 mutiplier?
my cpus stock run a 25x multiplier and I dont even use that, running 24 so I can run a bigger bclk for faster memory.
if I get the better cpus, is it possible they are more stable or something? The ones I have now, at least one of them is hard limited to 4.5~ghz.
I have two xeon x5680 and It's sitting at 24x multi, 189mhz bclk. ram is no issue since it still posts at like 23x and 197 with 4 out of 6 ram sticks working lol.
That's all I see from is that 4531mhz, I can throw +200mv at it and it might do 4.6 but it doesnt get any better of a benchmark somehow.

like the x5690 would be the top cpu and go for $30ish, but I can just buy a bunch of x5680 for $12 each and try to find ones that oc a bit higher.
which is the best idea?

Im guessing this is just for fun? Cause used 3600(x) are 50$ with 3100/3300x/3500(x) going for even cheaper and used midranger b3/450 like the gaming plus/tomahawk for ~50$ or less and even the 3100 will crush that overclocked x5680, and the board should still be worth like 30-50$ depending on how much x58 has derpeciated in your area and what board it is

 

Prefer bclk at 210-220 and lock the rams to 10x multi, 2100-2200 ddr3 is still really slow so unless you are using trash rams should be no issue hitting those speeds, but if ram speed is your aim get a xeon w as they have unlocked ram multi, ~2600 is what you can expect on a board that forces 1.5:1 uncore memclk (3900 uncore at ~1.45v) but 3400-3600 seems to be attainable on a board thatll do 1:1 uncore like gigabyte though youll need to actually find a board thatll handle 3000+ on the 3rd channel

 

 

As for the cpu id reccomend a w3680 due to unlocked ram multi and the unlocked cpu multi, think these should be binned higher than even an x5690 since theyre the xeon counterpart of the i7 980x, though youll have to bin lots of these if you want a decent chip, it helps if there are sellers places you can visit directly to oc test the cpus yourself so you dont have to buy a ton of em, afaik uncore and cpu freq are tied in terms of binning so a chip thatll do high uncore should also be good at high freq

 

Past a certain point cpu multi is pretty useless since you wanna be running 210-220 bclk anyways, pcie freq set to 115 but prefer higher if possible, scales with vioh pcie volt southbridge core and data volt

 

What volts and temps are you running at anyways for these 2 xeons? And also what mobo alongside settings? you can keep pushing volts into em as long as you have the cooling and they do scale with better coolers so even at >1.6v you may still see decent temps given a beefy enough cooler

 

 

Uncore ideal volt is around 1.45-1.55v since thats where it seems to get the highest freq before diminishing returns, with my average sample x5660 before i sold it 3900 at 1.45v and 4100 at 1.55v or 1.6v iirc and pushing higher is only for ram freq, i have not durability tested 32nm yet so no idea on how high you can push volts other than the general 1.6v max reccomendation for both vcore and vtt, 45nm however seems to take >1.7v just fine as for whatever reason my i7 930 is still fine even if i run 1.83/1.87v vtt through it for 3184/3200 ddr3 boot attempts and no degradation either cause if it did degrade id notice it immideatly since i do ram freq runs on it

 

As for ram tuning youll wanna identify the ics, 2gbit ics are preffered over 4gbit due to lower trfc (~100 vs >300), besides 2gbit samsung d die is pretty common in oem bare pcb form (m378b5773dh0 2gb or m378b5273dhp 4gb), hynix cfr is also available (hmt325u6cfr8c for 2gb and hmt351u6cfr8c for 4gb) but i wouldnt reccomend that since my 2 double sided 4gb sticks sticks top out at 2800c11 stable at 2.1v and going over 2v seems to degrade them which is pretty pathetic for a platform thatll handle 2.6v+ ddr3 (yes the 1.65v ddr3 max and 0.5v diff between vdimm and vtt alongside 1.35v vtt max is bullshit and my x58 setups are living proof of that), trfc hardwalls at 100 at speeds over 2000 but it seems like you can still run that low trfc even at 2800 just that my sticks were maxed out and trfc does consume abit of volt so had to run at 125 instead of the 102 id usually set. Im not sure of how samsung 2gbit d die behaves but all i know is that its better than hynix cfr and it shouldnt degrade at >2v which is prefferable, maybe it doesnt even have that 100trfc hardwall and i can go lower, heck i can probably try 3000 ddr3 stable with those

I think the cpu memory controller is shitting out at 1970, at that point it boots and works but two ram sticks just dont show up. it doesnt seem to affect cpu performance.

This is my first time even hearing about that what. Why does no one ever even mention these cpus when it comes to x58 platform. I'll buy two of em immediately.

1.56v for the past few years, it takes it, 90c in synthetic benches and like 75 in games.

I'm running 6x 8GB sticks at the moment and need the capacity. to do that I would need to run 12x 4gb and that sounds very ill advised

Unfortunately on the ram side the board itself only goes to 10x multi, I'm not sure if I can get more with the x3680s but I'm going to see when they show up
Oh, and board is a evga sr2, so the other problems are the bios is janky with these.

Ah well uh, I should have read earlier that the motherboard chipset does not support 3600 cpus and 3600 cpus don't even support dual socket configuration, they only worth with x58

After I took apart the pc and put them in too (

I guess I have cpus to try in my x58 now

 

 

It needed thermal paste though. Oddly it did not impact temps under load but it significantly lowered idle temps. Same temp in cinebench same score

Look at how burnt and messed up this looks though!! not good
