mac_shinobi Posted February 19, 2015 Posted February 19, 2015 @Arthur / @Sunnyknight and others have been helping with my PC. I have purchased this RAM Kit from MoreComputers . com however so you can see the item, I am posting the scan link : Corsair Memory Vengeance Pro Series Silver 32GB DDR3 1866 MHz XMP Quad/Dual Channel Desktop - CMY32GX3M4A1866C9 - Scan.co.uk On Speccy and other utils it shows max bandwidth as PC3-10700, the DRAM Frequency which is updated in real time in speccy and other utils and without Hyper V installed shows as 933.2mhz ( give or take a bit ) I'm not understanding why the max bandwidth is showing as PC3-10700 - have I been sold the wrong ram kit ? Updated the BIOS to the latest revision which I believe is 2205, taken all the memory modules out except for one memory module and still the same. Put all the memory modules back and reset BIOS / UEFI to factory defaults and then only enabled XMP and ensured that DRAM Frequency was set to 1866 Mhz Motherboard I have is the Asus Z97 Sabertooth Mark 1 I was expecting Max Bandwidth to show PC3-14900 and not PC3-10700 like it currently does. If I have missed anything then Arthur should be able to elaborate and or explain this better. If you require any photos of anything then can do that or video clips on youtube etc
Steve21 Posted February 19, 2015 Posted February 19, 2015 Isn't that right? 933 on dual channel is your 1866? Steve
mac_shinobi Posted February 19, 2015 Author Posted February 19, 2015 Isn't that right? 933 on dual channel is your 1866? Steve Am sure the memory I have is meant to be PC3-14900 and not PC3-10700 so DRAM Frequency is correct although why is it showing up as max bandwidth at PC3-10700
Steve21 Posted February 19, 2015 Posted February 19, 2015 Am sure the memory I have is meant to be PC3-14900 and not PC3-10700 so DRAM Frequency is correct although why is it showing up as max bandwidth at PC3-10700 Unless it's changed things like CPU-Z etc only read the SPD on the memory, so it's "default" boot speed is what it classifies as the max, even though it can run higher.

Nothing to worry about then? http://a.pomf.se/wtvvwp.jpg http://a.pomf.se/amjxvf.png 1
mac_shinobi Posted February 19, 2015 Author Posted February 19, 2015 ok that's fine - bit depressed as was hoping to see it show up as PC3-14900 or there abouts. Almost feels like I have been sold slower ram lol ok will leave it as is then.
Steve21 Posted February 19, 2015 Posted February 19, 2015 Nothing to worry about then? Unless I'm being silly and talking rubbish, it is one of those mornings haha But pretty sure it hasn't changed on CPUZ etc. The 926-933 would be the half rate (as double normally) so 1866~ And the SPD 1333 would be 10600 (10700 if one of those companies who round up ) Sorry mac No shiny numbers for you!

Arthur Posted February 19, 2015 Posted February 19, 2015 (edited) And the SPD 1333 would be 10600 I guess the reason why my DDR3-1600 RAM is showing as having a max bandwidth of "PC3-12800 (800 MHz)" is due to Crucial programming the SPD differently than Corsair? Corsair must be playing it safe by setting the default speed to 1,333MHz (667MHz). http://a.pomf.se/uuzdcl.png Edited February 19, 2015 by Arthur
Sunnyknight Posted February 19, 2015 Posted February 19, 2015 My dear mac.... you worry too much lol.
mac_shinobi Posted February 19, 2015 Author Posted February 19, 2015 (edited) My dear mac.... you worry too much lol. Paid a lotta money for fast RAM and then for windows utils etc to show that it is PC3-10700 instead of the advertised PC3-14900 or similar. Edited February 19, 2015 by mac_shinobi
Sunnyknight Posted February 19, 2015 Posted February 19, 2015 Screenshot from cpuz or any relevant software.
mac_shinobi Posted February 19, 2015 Author Posted February 19, 2015 Screenshot from cpuz or any relevant software. Will open Aida64 , CPU Z and Speccy and try and do one large screen grab and attach it this evening Thanks @Sunnyknight
mac_shinobi Posted February 19, 2015 Author Posted February 19, 2015 ok see attached screen grabs @Sunnyknight
difinity Posted February 19, 2015 Posted February 19, 2015 When CPU-Z is showing SPD speed that is not the speed of the memory but the default speed it knows it can run the memory at and thus boot. I wonder if it's showing it as PC-10700 as the frequency is 932Mhz which is 1864Mhz which isn't quite the 1866Mhz which would be Pc-15000.
Arthur Posted February 19, 2015 Posted February 19, 2015 the frequency is 932 MHz which is 1,864 MHz which isn't quite the 1,866 MHz @mac_shinobi has been cheated out of 2 MHz. Send the RAM back straight away!
mac_shinobi Posted February 19, 2015 Author Posted February 19, 2015 Cpuz part one shows 933.2 mhz so whys the other tab showing 932 ??
Sunnyknight Posted February 19, 2015 Posted February 19, 2015 Nothing wrong with the ram by the looks of those ss. Its fine. 1
DMcCoy Posted February 20, 2015 Posted February 20, 2015 slight frequency fluctuations are normal. Also, use something less terrible than AIDA, like HWiNFO 1

Arthur Posted February 20, 2015 Posted February 20, 2015 Download link for HWiNFO? Portable: hw64_450.zip Installer: hw64_450.exe Website: hwinfo.com The portable version doesn't require installation. Just unzip and run. 1
mac_shinobi Posted February 20, 2015 Author Posted February 20, 2015 Portable: hw64_450.zip Installer: hw64_450.exe Website: hwinfo.com The portable version doesn't require installation. Just unzip and run. Will try this tonight - Thanks everyone !! LOL @ Cheated out of 2 mhz
featured_spectre Posted February 20, 2015 Posted February 20, 2015 There isn't anything wrong with your RAM, it looks right at where it should be (give or take a mhz or 2). I'd be happy with that if that is what I paid for. You can clock it up a bit if you want to get more juice out of it as it has a max frequency it will run, so there is always that option if you want to squeeze a bit more from it. But I don't know what you'd be running that would warrant such action on a decent RAM stick. 1
