can't quite get the memory timings
on my OCZ silver PC2-6400 800MHz RAM there is a sticker saying that i can achieve 4 - 4 - 4 - 15
but i have yet to be able to achieve this, even at 2.2v.
is this because of my motherboard, bad RAM chips? voltage too high? voltage too low?
has anybody had this problem before?
i have been able to achieve 5 - 5 - 5 - 12 though, which is better? 4 - 4 - 4 - 15 or 5 - 5 - 5 - 12?
check my system at the side to see my system
CPU-Z Validator Database
also please use that if it helps.
Re: can't quite get the memory timings
4-4-4-15 would be better but quite honestly it won't really make a huge difference.
Have you tried running memtest?
What power supply is it that you have, sounds cheap and generic from "My System" I suppose it could be causing you problems.
Re: can't quite get the memory timings
i just want to get what i paid for and the most from my machine becuase i don't really get to upgrade often and like to have the best i can get when i can get it.
i've tried setting up memtest but i don't have a floppy drive installed so i dunno how i'd do this :S
i'm a bit of a noob when it comes to stuff like that. i'm still learning all this stuff.
the PSU is branded Casecom ATX500w Casecom Silver 500W ATX Power Supply - 20+4pin ATX12V 4x Molex - Ebuyer
it came with my case, but soon i want to buy a new case so hopefully i will get a better PSU with my case or buy a case without a PSU and get a very good 1.
what voltage should i be running the memory at for 4 - 4 - 4 - 15?
2.1?
the stock was 1.8 and the best i could get from that was 6 - 6 - 6 - 18..
OCZ Technology | Products | Memory | OCZ DDR2 PC2-6400 Platinum Revision 2 Dual Channel
that is the exact memory i'm using, it even says it runs at 4 - 4 - 4 on the website aswell..
something must be up with the mobo or something
Re: can't quite get the memory timings
That PSU tbh is garbage and wont be giving anywhere near 500W, at least not on the 12V rails where it is most needed (basically all components run off 12V rail). I wouldnt be surprised if it was undervolting your memory.
However, OCZ ram often needs higher volts. That psu definitely needs changing cos if it were to go wrong it could take ur whole system with it. Something from a known manufacturer would be more suitable, eg. corsair, seasonic even the xclio psus arent bad for a cheaper option.
Re: can't quite get the memory timings
how long do you expect it would last running my current system seeing as i've had it since christmas?
it's my birthday next month, was hoping to get a new case and PSU, the things i had to save on to get the internal parts that i wanted..
Re: can't quite get the memory timings
Its a risk I personally wouldnt take, that psu could fail at any time. Especially considering you have a fairly high power system.
The thing about PSU's is that the manufacturers lie, the wattage is rarely accurate on a cheap psu or if it is they put all the power on the 5V and 3.3V rails which is totally useless to a real system.
Look at this and pick one from a recommended manufacturer:

Re: can't quite get the memory timings
I`m not really au fait with the Nvidia `boards, I take it that the memory controller is in the Northbridge, if so, is it worth trying to up the volts slightly to that?
Re: can't quite get the memory timings
i've just looked at this
OCZ StealthXtream 500W PSU - Ebuyer
it has everything i need, the PCI-E
the 2 SATA powers
it's perfect.
would it be stable and reliable with it being only £40?
which tier do i want to be looking at on that website?
i'm willing to spend upto maybe £60.
if that's what i need to be able to afford it.
so with my PSU being so cheap does that mean it'll be undervolting my RAM and CPU? i have my GFX card plugged in through 2 molex's..

i didn't think of trying that, i'll try it, thanks :)
Re: can't quite get the memory timings
I dont know much about that OCZ PSU, OCZ do class it as a value item which means it may have a slightly lower build quality. This seasonic would more than do and would give reliable power for a long time.
Seasonic S12 II 500W PSU - 12cm Fan 80Plus Efficiency - Ebuyer
Or this corsair one which is made by seasonic:
Corsair VX450WUK 450W PSU - Ebuyer
Re: can't quite get the memory timings
that 450w one looks good, but it works out more expensive than the 500w with delivery 'cause delivery on the 500w is free. so i think i'm gonna get that Seasonic one, looks very good, has everything i need but i can't really work out if that is 1 SATA power connector or 2 on there
3rd from the left and the very left 1..
i'm actually quite worried about my PSU now, is there anyway that i can hopefully extend the life of my PSU
and what features do these more expensive PSUs have that stop them breaking or destroying my computer?
Re: can't quite get the memory timings
Its all about build quality, its like driving a ferrari at 150mph or driving a skoda at 150mph. You are within the limits of the ferrari but exceed that of the skoda.
The seasonic actually has 6 SATA connectors btw. Very good choice.
Re: can't quite get the memory timings
What about the 520HX Corsair, slightly overbudget (£65) but free delivery from Ebuyer (I think) or free next day delivery from Novatech:
Corsair HX520 520 Watt PSU : csr-hx520

Re: can't quite get the memory timings
the main problem with this whole thing is budget.
i could only afford this computer becuase christmas came along, i won on some capital bonds thing ym grandma does for me and i sold my PSP and about 25 games. And i had also saved a lot of money up through the year.
i think i'll go with the cheaper Seasonic 1, just becuase it has enough SATA connectors if i get another HDD or DVD drive or anything like that, and becuase it's cheaper. thanks for the help guys, but does anyone know how i can get 4 - 4 - 4 - 15 on my RAM?
we went a bit off track..
but at least i found out that i need a new poer supply and quickly.
Re: can't quite get the memory timings
i like that what you wrote about my sig. i just thought it was extremely strange and just wrong.. why the hell is it beige and how did they do this experiment to find the colour of it 'cause light will never reflect off the universe to show us its colour.
Re: can't quite get the memory timings
Voltage: 2.1 is probably the right voltage for that memory (providing the PSU is supplying it). I think OCZ can handle extra as well as any memory, but it shouldn't be necessary. 1.8 is "stock" for the mobo, not the RAM, so you shouldn't run it at 1.8.
Are you Overclocking? If so by how much? Also what is your motherboard. Your system says NVidia 680i, but that's the chipset, not the maker.
