    BIOS Configuration for Ram - Help a Noob out please

    The i5 cpu needs to be overclocked. The i7 cpu does not need to be overclocked to reach 1600, because it allows the 12x memory multiplier. 12 x 133 = 1600. For the i5, more than once I've seen the blck raised from 133 to 160. Then the 10x mem multiplier = 10 x 160 = 1600. Running at blck = 133...

    BIOS Configuration for Ram - Help a Noob out please

    You get more accurate results from reading the Bios. Anyway, there is about 1% performance advantage for ram speed 1600 over 1333. When your timings are lower, your memory is more efficient. When you changed to XMP, did your timings change to 9-9-9-24? 1600 is not automatic for an i5, so I...

    Issues booting OSX and XP seperate drives

    That's an interesting idea. I always installed Windows to the first drive when I dual booted with Redhat. That is when there was a primary and secondary ide port on the mainboard. Out of force of habit I still install Windows 7 on the sata cable #1, even if it doesn't matter. If he has XP...

    Issues booting OSX and XP seperate drives

    Your boot files for XP may have been overwritten. If you have a newer Bios, then I think F12 will often let you boot a different OS directly from the Bios. Or, you can unhook the SL drive and see if XP boots, the only attached drive. If you can't boot XP by either of these methods then you need...

    OSX Won't Boot After Windows 7 Install: Please Help!

    Buying a second hard drive and having Windows on one and SL on the other is a very good idea. The different boot files can be written to the MBR of each drive separately. If Win and SL share the same hard drive on different partitions, it's possible for them to not sync. It is safest to install...

    My first SB build Hackintosh...

    Some of the older 1.65V ram may work, so with that older ram I would test it first to see it it is stable at the lower voltages recommended before buying new ram. But if you are buying new ram, then it is certainly more prudent to buy ram rated at 1.5V, not 1.65V...

    SB 2500K/2600K Build(triple display): CS5, Gaming, AutoCAD

    I think a consideration regarding what is the best cpu cooler is having a large enough case for it to fit into. Some of the graphics cards are also pretty big. I picked a Haf-932 because it is roomy enough for my big hands and comes with 5 fans. I chose the V-8 cooler at $52 (for 1366) and my...

    USB oddities and sleep problem

    I think the most economical approach is to try the Overclocking Forum. More than one guru person has stated that both of you must overclock with your mobos and especially the i5-760 cpus, in order to get your ram to 1600 speed. That's true even with different brands of ram. This thread in this...

    Non-overclocked i7-950 Overheating

    My cpu temp was always a little high. Then I had a spontaneous reboot so I checked my temps again and they were much higher. When I separated the stock cooler and cpu I found that I had done a bad job with the thermal paste. The recommended way is to apply a largish grain of rice to the cooler...

    USB oddities and sleep problem

    After Stork posted that he had symptoms on his other OS, Windows and Ubuntu, I thought it would likely be bios settings since the bios controls behavior for all of the OS. I tried XMP on my mobo and then disabled it. iirc, the default voltages from XMP were DDR = 1.65 and the QPI? voltage was...

    [DualBoot] SL & W7 on the same hardware, same HD

    http://thegadgets.net/trickt-boy/tips-a ... 7-on-a-pc/ You can install the OS's in either order. You would be better off getting another drive. Because when both OS are on the same drive, the last OS installed overwrites the bootloader of the other OS with its own bootloader. So if you install...

    USB oddities and sleep problem

    I am pleased by your news! Doesn't one expect a faster transfer rate from USB3 than USB 2.0? I haven't gotten a bluray burner yet but I think the Sony is a good choice from what I hear (you were in that thread). It took 10 weeks for my rebate checks to arrive from Corsair, one for PSU and one...

    Sandy Bridge Builds?

    If you buy the i5 760 the multiplier for that cpu is 10x. So don't buy memory over 1333 (10x 133) because to use 1600, you must OverClock. the 9xx cpus (1366 MB) have a multiplier of 12x (12x 133) = 1600 so don't require overclocking the cpu. But there is very little performance advantage to...
