|
 |
Hey guys had a little question i hope one of you can help me with.
I was running 6gb of stick dell 1333 ddr(2x2 and 2x1). got me a 2x8gb set today (ddr3 1666) but since im still stuck on this motherboard for now i can only software overclock(which is shit ofcourse). so i can only get about a 330mhz overclock. (i5 750 2.8 to 3.1something)).
Now my question is the following. Do you guys reccomend running with the 300mhz overclock(it is stable) or adding in the other 2x2gb sticks to have a total of 12gb ram?
Would I see any performance increase from either of the options to begin with lol?
The new sticks are corsair vengeance, so I reckon the timings on that are alot better than the stock dell sticks, will pooling them bring the timings of all sticks down to the dell level?
Thanks in advance

You should have bought kit which is made for X58 (triple channel). Do not add the 2GB sticks (never mix up ram like that).

Board doesnt support triple channel. the 2x2gb is a dual channel kit too, whats the reason not to mix them?

Different timings, different voltage, different SPD/XMS profiles, different chips.. Can cause a lot of issues.

well its all 1.5v ram. the timings are diff but i think its at least 9 on cas latency for both pairs for the speed it would be running at. What was in here stock were 2 sets by duff manufacturers(came stock from dell) and never had an issue(altho they prolly paired it for a reason).
seeing as i can only get a very small overclock without any Vcore controls, is it a given that i'd have issues if i'd mix the ram or is there a fair chanche it would work too?
is there any lasting damage i can do by trying?

You really won't see a difference either way. The 8gig to 12gig won't make a difference unless you open multiply applications at a time to fill up the 8, let alone 12.
The 300 mhz increase might be a slight improvement and most likely the better option. The extra ram won't make a noticeable difference.
If you do go down the path of the increased ram just remember to pair them correctly to get the dual channel. You'll need 4+2 in the one channel and 4+2 in the other.

ya ill just seat them the same way the dual channel set was set first.(have to like x them, 2-4 2-4, so now with the 2x4 i have one in slot 1 and 3 when you look at it(these are marked slot 1 and 2 ) but first want to make sure there is no permanent damage that can be done if the rams dont like each other. I edit and photoshop alot so the ram might be usefull, but not if it will mean less performance from the other ram. Think I might be able to get this overclock with the 12gb too.

Sorry to bump this but really want to know if I can try this without causing any damage to the sticks/slots/mobo If it wont work.

If all the memory sticks are properly supported by your motherboard (voltages and all), there shouldn't be any damage.
You can't damage the PC by running compatible hardware on it (unless it's broken in some nasty way). At worst you will simply have stability issues.

i would do it. i havnt mixed ram on any current generation systems, but over the years i have done it a lot and never had trouble. the 'problem' is that they all run at the speed of the slowest stick. if you put a 2 gig stick of 1066 into a system with 8 gigs of 2133, you would lose half your memory bandwidth in exchange for only 2 more gigs...in your case, the difference in speed is negligible, considering you are getting 1/3 more memory (and it would likely be offset by the overclock, if you can get that too).

havent had a chanche to try it yet. how about performance decrease becuase of timings? since one is cheap dell memory the other vengeance with decent timings, will i lose any performance there?
been trying to get my hands on a 1156 motherboard around here but damn are they hard to find... finnaly found a sli one. but guy who sold it said slot 1 doesnt work, *sigh*

Aye a day like that (with some intensive rig cleaning, my laptop HD is such a mess these days lol) has been in the works for a while now, but have yet to find the time =( Will post results when I get to it though, maybe wedenesday. Been looking for a 1156 board but really looks like that isnt happening.
people been getting decent results on the i7s with this crappy dell board and setfsb, not sure why mine wont go higher. Had an issue with the windows clock timer messing things up(messed up my sync in games) fixed that , havent tried ocing further after, maybe it can go higher now.

something to try when you have everything half apart is run/benchmark/overclock the two different kinds of ram separately. one set might overclock better, in which case you might be able to get more speed with less (faster) ram.

ya the dell ones dont overclock much altho i dont think it made a big difference with the new ram, so then there must be something else being stubborn, or this board just wont get me anywhere. guess soft overclocking is a very flaky thing
edit: the windows clock timer fix didnt make me able to push it further. 148 is fine and stable for 12 hours on prime. then if i go from 133 to 150 it bsods, (but from 148-> works fine till 152/3) then it bsods.
Is this the cpu jus bein a bad seed or the motherboard being a dell dick, or not enough info to be able to tell?
