i havent looked at the physical ram yet i need to remove it from my machine to see what the stickers say but on the box it states the ram speed i purchased

but i purchased this ram on tuesday
http://www.overclockers.co.uk/showproduct.php?prodid=MY-008-PA&groupid=701&catid=8&subcat=1389
and i notice in the part number for this ram it reads PVT36G1600LLK

cpu-z says its
pc3-8500f (533mhz)
part number 1333LL series
and the xmp profile is 1333 also

no matter what i try it will not run at 1600mhz


hoping someone with this ram can post there cpu-z part number
 
No. You don't have the wrong ram. You are running the ram at a lower multiplier, so it is underclocked. Increase the memory multiplier and/or the bsck to get it to 1600mhz.

This really could have been solved with a search, some of the most common threads on here are 'oh no, I don't understand speedstep' and 'oh no, my ram's underclocked'

Neither link works, but I can guess what you mean. One is rated to work up to 1600mhz. The other is rated to work up to 1333mhz. Either set will attempt to run at whatever your motherboard asks of them. The difference is either none or speed binning, the 1333 one might run fine at 1600mhz but the 1600mhz one definitely will.

Increase the memory multiplier in the bios, or accept that it's running slower than it can.
 
no what im trying to say is, have i been given the wrong ram to what i paid for, i paid for the 1600 version yet everything i can find out about mine is that its the 1333 version, the links are to patriots product page for both sets of ram, will try and fix them

anyone reading this pay close attention to the product numbers, i believe i should have the 1600LL part and i have the 1333LL part

and why would i accept ram running slower than what i paid for it to do, now if the cpu can't handle it that is another story but the ram should always run at it's rated speed

Cpu-z is going to report what it thinks the ram is. It tells me my 1066mhz reaper is 800mhz reaper when its running slowly, complete with 800mhz reaper part number. Either turn the multiplier up, or unplug one of the modules and verify for yourself that it has 1600mhz written on it

If it doesn't, patriot have put 1333mhz ram in a 1600mhz box, as you state the box has the correct speed written on it. They haven't done this, the odds are crushingly against you here
 
no the part number should never ever change as that is programmed into the chip

max bandwidth reported pc3-8500f (533), that is programed into the memory that should never change

my I7 is running at 3.8 gig atm and it is programed to say 2.66gig
 
Several speed & latencies are written to the chip, not just one. Cpu-z can only report the one currently being used.

The part number on the box is more reliable than what cpu-z reports. Are you yet to read the sticker on the ram? I'm getting slightly frustrated here

The i7 is told to boot at 2.66ghz at a certain vid by default to make sure it works in any board. Your ram is also set to boot at 1333mhz by default for the same reason, you have to change this manually.
 
i have checked the ram and it states what i should have, my system is booted at 1520 atm yet cpu-z still only reports the max speed is slower than what it is running

i have only one xmp profile in the bios to choose from and that is 1333, not 1600

i know what reported speed is and where it tells you all the info about your ram sticks is
 
So the ram says you have 1600 mhz ram. And the box says you have 1600mhz ram. And you ordered 1600mhz ram. Yet you don't think you have 1600mhz ram. Perhaps I should leave you to it at this point

The highest multiplier available in the bios may well be x10, which would give you 1333mhz for the ram. So put the bsck up to 160 and it'll be at 1600mhz. This is overclocking the processor and carries the standard risks of instability.

If you do not want to overclock the processor, then you have foolishly purchased ram faster than your system can make use of.

From my first reply.

i have ran it at those speeds and they do not run, i have my system completly stable at 1520 with a 3.8g overclock, ran intel test for 3 hours stable and prime all night long, even increasing the multiplier on the ram and lowering the cpu speed they will not run at 1600 speeds

i have no xmp profile for 1600 either, only 1333

i know what overclocking is and i have done it for years back since the duron days,

i am just confused as i expected the same results from cpu-z as all my other ram as in it tells me its max speeds and the programed settings, the brief reading i did lead me to believe i should have a xmp profile of 1600 in the bios as this will auto set certian settings also, yet i only have a 1333 profile showing, latest bios for the motherboard

Oh thank heavens, I'm sorry for being so patronising. If the issue is that the ram is not stable at rated speeds, that's completely different to you not being able to work out how to get it to run at rated speeds.

I take it you've put the voltage to 1.65V, and the ram to 1600 using the multiplier while keeping the processor at a known stable speed? If the timings are also set correctly (cas 8 or 9?) and it fails memtest, then you have grounds to return the ram.

Which motherboard do you have? My experience of incompatibility is that the ram works fine, but not at full speed. I had some 1066mhz ocz that wouldn't run at 5-5-5-18 at any speed above about 950mhz in a G35 board, could only be solved by changing board or ram
 
i have a asus p6t deluxe v2, latest bios installed on it

i can throw what ever i like at the machine with the ram at 1520, voltage is at 1.66 wont let me choose 1.65 timings are 8,8,8,24

cpu multiplier is set at 21x190, with 1.26v in the bios

soon as i put the ram to 1600 it fails everything even with the cpu at a much lower speed

again i know am going on about it, i have no profile for 1600 ram, only the one of 1333 which is why i think the ram is wrong


and dont worry about being patronising, 6 year member here or so and 150 post hehe, i hate forums and can never type whats in my brain

screen shot also to hopfully explain, as you can see there is no xmp-1600 profile listed, and the part number is showing 1333LL series, would have expected that to say 1600LL
 
without any direct experience or time to read up and erring towards the op.

Surely the os or bios doesn't know part numbers for ram? It must read that off the chips? I think i understand about the max speed reported being as what the bios is telling it to run at but then linking that to a part number in it's database?
 
Shrug. You may be right, issue remains either way. Either they've sent you 1600mhz ram that can't run at rated spec, or they've sent you mislabelled 1333mhz ram which can't run at 1600mhz. I'm not sure there's a difference, it's going to be an rma either way.

It will help your case if patriot are listed on the memory compatibility table for the motherboard, but shouldn't matter if they aren't.

Makes me a little bit glad I bought corsair instead, I wish you luck with the rma process :)
 
phone call to overclockers not very helpfull :( shame that part of the service is the same through out the years

a quick visit to the store though and one happy camper here, ram found to be mislabeled and unstable at 1600mhz,

switched to corair 1600 and now stable at desired overclock of 200x20 :)

thank you for assistance in the tread
