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

also please use that if it helps.
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.
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
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.
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..
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:
Official XS Tiered PSU Manufacturer Brand Listing Phase III - XtremeSystems Forums
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?
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 :)Quote:

Or this corsair one which is made by seasonic:
Corsair VX450WUK 450W PSU - Ebuyer
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?
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.
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
"scientist belive the universe is in-fact beige" That`s why they should never be trusted...............
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.
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.
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.
I`m sure that the Seasonic will be fine, just like to give you a choice.
I was under the impression that nothing has colour as such, only the spectrum of light reflected from its surface gives us the illusion that the pink elephant sat next to me is pink....Damn it`s gone. Although that may be due to the fact my PC cooler has at last descended to zero kelvin!
i have the XFX nForce 680i, i like to get my motherboard and graphics card from the same manufacturer so that's why i went for this.
i don't usually overclock anything but i have tried overclocking my CPU and i have slightly overclocked my graphics card just because it only raised the GPu temp by 2'C.
i don't really know how to overclock RAM..
only the timings of it.
If modular is not an absolute then look at the Corsair VX series, 550 watt. 41 amps on a single rail.
I am in the process of building for a m8 a quad 6600 2 GB ram 2 HDD and a 8800 GT.
Currently soak testing with prime 95 it hasnt missed a beat.

Reading that yes you are:)
when you say modular do you mean the ability to be able to remove cables from the PSU when you don't need them?
i might take that into consideration, need to see how much i get for my birthday first, 16 years old :P, march 9th.
i also want to get another 8800GT and SLi them so i also need the new PSU for that i'd reckon..
if you have time could you please explain this amperage thing on the rails to me?
i do systems & control at school and we do this kind of stuff but i don't understand how a higher amperage is better..
First to understand why more "Amps = good" you need to understand a few things firstly power is measured in Watts (guessing you know that :)) and Watts are a product of volts and amps so
volts * amps = Watts
Now if you have a 12 volt supply which can provide 120 Watts then the supply is rated to 10 amps if it can provide 240 Watts then its rated at 20 amps.
Hopefully you can see that more amps means more available power, at a given voltage.
Rails are actual or theoretical splits within the PSU which mean that you have 2 or more 12v supplies so if you have a single rail it may be able to produce 30A (360W) or you may have 2 rails which have 18A each so a total of 36A (432W) these rails however are limited to 216W on each rail so if you exceed the total power for a single rail that would be bad, the rails could be distributed to provide 1 for the PCIe connections and the other for everything else, for example.
As you guessed modular means that you can remove cables that you do not require or rather only plug in the ones that you do! This means that you will have fewer cables in the case so it should be tidier, and a tidier case is a happier case!
Hope this helps.
right.. i understand that much better now :) 12v rail with 40A = 480w?
the higher the amperage on the rails the better?
thanks for the help :):):)
personally I would stay clear of SLi. Why you ask?
Well the gains versus expense. On average you may gain a 1.5 increase in speed ie Frames per Second this is game dependent if it wrtten into y=the driver to support that game.
To obtain a visually smooth frame rate 60fps is the general rule, depending on what monitor you are playing on and therefore the resolution a single card such as the one you have is more than capable of giving sooth performance up to a 22 inch LCD.
By the time you come to get that second card a newer generation of card will be out that will provide even better performance.
Evidence of that is the current 8800 GTS 512 G92, this will come within a few frames of the G80 8800 GTX that I paid £400 for early last year:surprised:
A GTS can be got for £200, see my train of thought?
Get a trial copy of FRAPS run your GT on your favorite game and see what framerate you are getting, hopefully that will provide evidence that you dont need SLi.
yes, 62FPS i'm getting on average on CoD4 on all very high with AA off.. i see what you mean, good eye candy then, just about it.. and by that i mean inside the PC..
i'll keep my money and buy a good case and silent fans and a good PSU then
and maybe an extra 2GB of RAM.
Overclocking the CPU means increasing the FSB. That also clocks the RAM higher, but I would expect the RAM to be well within its rating unless you did some serious overclocking.Quote:

If neither I'd blame the mobo, but it will be hard getting an RMA.
