Hello, there is any1 who knows how low i can go with stock speed on latencys ?

i don't want to oc the speed, but i want to make it faster with low timmings...

can some1 give me some support on it?

Gigabyte x58-UD3R
HD5850 @ 925-1175Mhz

It's hard to say how low can you set timings. All depends from IC and it can vary depends from batch/series or manufacturer.
Probably you have there Hynix IC but I'm not sure. Anyway try something like this:
8-9-9-24
8-9-8-24
8-8-8-24
7-9-8-24
7-8-8-24

I doubt you can set them much tighter and for some of these settings you may need to raise voltage up to ~1.60-1.65V. Try to play some with sub timings too.
At least on this platform it won't help you much in general performance.

I'm running 8-8-8-21 on what appears to be similar RAM at stock voltage , but every batch , mobo , and CPU will have it's own quirks.

atm im running 8-9-8-21 too with 1.6V, maybe don't need that 1,6... but bumped it a bit to help stability.

Is that the RAM that specs at 1.25v ? Is that (1.6v) kind of high for that RAM ?

Woomack · Nov 20, 2014

Every memory has to be compatible with Jedec specification so at least 1.5V +/- 0.075V and up to 1.975V max for short period of time ( like unplanned spikes ). I don't think there are any 1.25V IC in mass production. All popular IC right now are 1.35V 1600 11-11-11 or 1.5V 1333 9-9-9 so 1.25V probably started as something like 1600 11-11-11 1.35V ( should be visible in SPD profile ) and after binning finished as 1.25V.
Simply 1.6V should be still safe.

Second one on the list and the one at the bottom. I'm WAY out of my league in this area , and Woomack would be the one I'd ask any questions I had concerning RAM. I'm just trying to get a little education from all this.

It's like I said in the last post. SPD is 1600 1.50V as auto/default settings. XMP 1600 9-9-9 1.25V

I have a lousy network connection (packet loss in the 70%+ range) and couldn't get the product links to open for any details. I had no idea RAM voltages could be that low at those speeds. That's impressive.
