Techquickie "Base Clock vs. Multiplier Overclocking" thread.

 Share

Thread is missing from the official LTT subforum, so I'll post it here.

 

First off, I'd like to say... congratulations! You guys made an informative video that I (a techie) was excited to watch!

 

Unfortunately, I don't think this was a great video for techquickie as base clock overclocking is much more complicated than what you made it seem. You made it seem nonviable now-a-day, when in reality that's untrue. You just need a certain motherboard. Some motherboards even offer separate PCIe/RAM clocks so that you can OC the baseclock as much as you want without causing instabilities. Now, knowing which motherboards do and don't offer this feature would have been a nice addition to the video, or even talking about which generations of intel/AMD chips supported this type of overclocking the best. (Skylake anyone?)

 

Finally, I would have liked to have seen benchmark comparisons (even though they'd be close to identical) for OCing a chip using baseclock then multiplier. 

 

I feel like baseclock overclocking is an iceberg, and you guys just barely touched the top. 

 

Also, wtf was up with the shitty audio? That's not normal for you guys.

I do believe this video is not meant for people who'd be willing to find out which motherboards can do base clock overclocking properly by doing a lot of research before purchasing, but for the general public who may not know much about overclocking and only look up some guide online that may be recommending this method on how to overclock, only to be left wondering what's wrong when nothing works properly because they don't have the right motherboard.

 

There's also only so much they can talk about in a few minutes, obviously they can't talk about everything in depth.

My brother's PC has an i5 7400 on a B250M DS3H, I want to give it a little bump so that it doesn't bottleneck his 970, and I really can't find any good BCLK overclocking guides. Is there any good material out there for me?

Honestly, it's basically 

 

  1. Strap your PCIe frequency to 100 MHz. Literally anything more than 103-105 will usually cause crashes. (PCIe runs at 100 MHz) This depends on platform, some platforms (like 775) had a separate PCIe clock so you didn't need to worry about it.
  2. Change your base clock.
  3. Look at how that would change your memory speed. Memory speed = BCLK * memory multiplier. This... depends on platform, but when you increase the base clock the memory clock also gets increased, unless you strap it to a lower frequency. Sometimes you can change the ratio of base clock to memory clock(the memory multiplier), and this can allow you to OC the baseclock more than your memory would normally allow.
  4. If the memory OC is inevitable (based on mobo etc.) make sure the memory voltage is increased to compensate. (Basically disable XMP until you're done and you should be fine, just increase the memory voltage a bit.) 
  5. Increase the VCore just as you would if you were OCing the multiplier. 

 

This seems like a well thought out (if a bit outdated) base clock overclocking guide.

I believe he's running a kit of 2133 so the memory overclock was inevitable. 

 

I think my biggest hurdle is to find the BCLK settings menu in the Gigabyte BIOS, so this should certainly help.

Can't BCLK off B250? that's a shame.

Even for BCLK overclocking? That's shitty. :( (Sorry I didn't know that, I only have Z170 chipset boards :( )

you can't change BCLK on any Intel board that's not Z or P chipset since socket 1155. Sky OC removes the need for the multiplier to be unlocked, and that's it.

Sorry all, not sure if i'm reading this right, but does this mean that you can OC a non-k skylake chip if it's in a z170 board?

I will only ever answer to the best of my ability - there is absolutely no promises that I will be correct. Or helpful. At all.

yes, but the sensors in the CPU go crazy and cache speed is reduced. It's also that a few boards that are unknown in this function, for example the Biostar boards.

OP brings up a point. Should the TQ videos be an informative short video about some topic or should it be video about demonstrating or performing an action?

 

i vote for the first one.
