OC from 2666-3000+

[Shipit]

Need my pc to do a few extra things last 1.5yr of univeristy. Looking to upgrade form 16GB/DC (8GB) DDR4 3200 to 32GB/DC (32GB) DDR4 3600 - its on sale

 

wondering if i could overclock from 2666 to 3000+?

 

main use is google cloud. Thanks all

 

Specs:

Intel Core I5-8600k Processor

9M Cache, Up to 4.3GHZ 3.6GHZ base - 2 Dimm, 2666 DDR4, max 128GB

 

Z370 KRAIT GAMING - (MAX SPECS) 64GB, typical speed on board 3200. These are from MSI themselves

 

MSI GeForce GTX 1070 Ti 8GB GDDR5 PCI Express 3.0 x16 SLI Support Video Card GTX 1070 Ti DUKE 8G

I mean, you can. I have a set of DDR4-2400 Crucial sticks that I've run all the way up to 3200 MHz, but the stock voltage requirements for the RAM are key. If it uses 1.25V by default, you have a lot of room to play with. 1.4V is my high-water mark, but I've heard of people going up to 1.5V on RAM with good heatsinks. If it's set to use 1.4V to get to 2666 MHz, well, that's a different story.

 

You may have to loosen your timings a bit, but as long as your RAM has a heatsink on it and voltage headroom, 3000 MHz should be attainable. Worst case, 2800 MHz is almost guaranteed on a stick that's advertised at 2666.

Its ic dependant

2133 samsung e die can clock 4600+ but 2133 unbinned samsung b die clocks like c die aka shit (3200-3600 problably)

 

Voltage requirements are also ic dependant and stock voltages do not play a part here, samsung c die does not scale with volt whilst ics like samsung bdie will take 2v+ and continue scaling then theres other ics like djr that top out at 1.9v

 

cooling becomes a problem at higher speeds (>4600) but lower speeds you should be fine, this is also ic dependant as some ics are more temperature sensitive than others, notably samsung bdie, essentially use as much volt as you need limited only by the ics scaling and/or cooling

 

Spoiler

 

 

This is 2800 ddr3 on a couple hmt351u6cfr8c double sided 4gb hynix cfr sticks, its a 2.1v overclock at 11-14-15 timings and only needs a mere 1.5v vtt at this speed on this i7 930, stock speed is 1600 ddr3, would do higher speeds with looser cl but x58 dont do >c11 unfortunately

 

X58 supposedly has a max vtt of 1.35v and a max vdimm of 1.65v but obviously thats complete bullshit, dont follow any one size fits all vdimm reccomendation as ics vary alot, many many crippled overclocks due to morons following these arbitrarily low vdimm and vtt reccomendations

 

So use as much voltage as neccesary, dont dump your voltage into cl as thats just wasting voltage for no performance gain and heating up your sticks where the volt could be used for tighter trfc and higher freq which do make a performance impact, but as a reference you should only need around 1.5v for 3800-4000 assuming you dont dump all your volt into cl

 

 

Btw what crucials? If theyre garbage like 8gbit rev b then rip but if theyre decent like 8gbit rev e/j then you should be able to get them up to around 4600 at 1.6v assuming you dont dump your voltage into cl
